Brass Check Valve
With a ball Brass Check Valve, there is a ball inside the shell that sits up tight against the side of the valve where the water will be coming from. In most cases, there is a spring that holds the ball tight up against the hole, creating a seal. When water is forced through the valve, it pushes the ball into the spring so that it can come through the opening and out the other side. When the water is turned off, the ball settles back against the hole and keeps water from flowing back the other way. A dual valve would have two areas within the valve with balls sealing them shut.
1 Disconnect your appliance from its power circuit. Do not just switch off the electricity to the appliance from the power circuit; remove the plug from the switch as well to make sure you do not suffer an electric shock.
2 Take your appliance apart to locate the position of the check valve. The check valve is typically a circular knob made of rubber located inside the machinery of your appliance. Use a screwdriver to disassemble the appliance and open any coverings such as for the vacuum booster. You may have to remove a number of parts from your appliance before you locate the Brass Pipe Fittings check valve. For assistance, refer to the owner’s manual for your appliance.
3 Inspect the check valve to see if it is loose or broken by trying to move it with your hand. If it is loose, the check valve will move by touch. If it is broken, this will be readily apparent.
4 Replace the check valve if it is broken. If it is loose, place the check valve between the teeth of a wrench and turn it in a clockwise motion until the valve cannot turn any further then give it an extra tight push. However, do not push too hard as you may cause damage to the valve or break it.
5 Reinstall all the parts that you removed earlier. Screw on the cases and coverings for the machinery that you previously removed.
6 Plug your appliance into the power circuit and turn the power back on. Switch on the appliance and make sure that it is functioning properly. It should now be applying proper pressure without any problems.

Bronze Check Valve Flow

Posted on April 19, 2012 by admin

Bronze Check Valve
Bronze Check Valve prevent the back flow of liquid or gas. Sprinkler and irrigation pumps often use check valves to stop water from draining out of the pump body when not in use. If the water flows out, the pump may require priming before it will siphon water again. Check valves are also used to prevent back flow contamination of water supplies to prevent flooding and prevent flow due to gravitational forces.
1 Find a bucket with a marked volume, such as a five-gallon bucket.
2 Fill the bucket with water from the outlet (tap) of whichever Brass Compression Fittings – valve you’re testing. Simultaneously, start a stopwatch.
3 Stop the stopwatch when the bucket is completely full, and note the time.
4 Divide the volume of the bucket by the time in minutes that it took to fill it. For example, if it took three minutes to fill a five gallon bucket then divide five by three. This is your flow rate in gallons per minute.

Repair Angle Valve

Posted on April 11, 2012 by admin

Angle Valve
Angle valves are a type of shut off-valve designed for pipes coming from your wall. When you begin to notice leaks around the Angle Valve, it is a result of faulty washers. Instead of replacing the angle valve, you can fix it. Repairing the valve is the proper thing to do, especially if the angle valve is connected to a copper wall pipe. You can disassemble the angle valve and replace the washers.
Leaks at the Supply Pipe
1 Determine whether the angle valve must be repaired or replaced. If a leak occurs at the connection between the water supply pipe (rigid pipe) and the angle valve or between the angle valve and the water supply line (flexible line that connects to sinks and toilets), then repair is possible. If an angle valve leaks from around the shank of its handle, replacement is more efficient and less expensive than repair.
2 To repair a leak at the connection between the water supply pipe and the angle valve, turn off the main water supply to the pipes. Find the main water shut off, and turn it to the “off” position.
3 Place a bucket beneath the angle Brass Float Valve. Close the valve by turning its handle clockwise, and remove the water supply line connected to the angle valve. Open the valve by turning its handle counterclockwise, and allow water to drain into the bucket.
4 When the water slows to a dribble, remove the angle valve. Attach a crescent wrench to the valve, and a crescent wrench to the water supply pipe. Turn the wrench attached to the valve counterclockwise. Hold the wrench attached to the pipe in place to prevent the pipe from twisting as you turn the valve.
5 Remove the valve. Use a wire brush, emory cloth and a rag to clean the threads on the valve and the pipe. Apply a double thick layer of pipe-thread seal tape to the male threads, and reattach the valve to the pipe. Turn the valve until hand-tight, then a quarter turn more with a crescent wrench. Turn on the water supply, and check the repair for leaks.
Leaks at the Supply Line
6 To repair a leak at the connection between the valve and the water supply line, close the angle valve by turning its handle clockwise. Remove the water supply line from the valve. Replace the old water supply line with a new line. Turn on the angle valve by turning its handle counterclockwise. If the leak persists, the angle valve must be replaced.
7 To replace an angle valve, turn off the main water, and remove it as in step 2 of Section 1. Clean the water supply pipe’s threads using emory cloth, a wire brush and a rag. Apply a double-thick layer of pipe-thread seal tape to the male threads.
8 Attach the new angle valve to the pipes by turning clockwise. Turn the valve until hand-tight, then a quarter turn more with a crescent wrench. Turn on the main water supply, and check the replacement for leaks.

Brass Gate Valve – Five Most Important Varieties

Posted on March 27, 2012 by admin

Brass Gate Valve
The prosperity of the valve industry has been shown on many aspects. In fact, a great variety of valves have been making their contributions to the development of the modern industry. The Brass Gate Valve, as an important member of the valve family, has done a lot of favors at shutting off the flow in many fields. It brings benefits for the daily life indeed. For example, the water faucet is the very common type of the popular gate valve.
Gate Valve- Classification According to Wedges
Different valves utilize different types of wedges and each valve is distinguished accordingly. The following sections describe some of the important classifications.
The flexible wedge valve: These valves include both one-piece and twin-piece disc to alter the angle in between the seats. The wedge valves are quite flexible and can be found in different varieties. One of the most commonly used flexible wedge valve is the parallel side valve which is used in the stem valves. These valves can expand and contract as it has the ability to withstand the varying climatic conditions.
Solid wedge valve: Gate valve with a solid wedge can be used for all types of liquids. It is suitable for turbulent flow as it is strong with a simple construction. With a solid construction in a single piece, these wedge valves are widely used in many areas.
Split wedge valves: These wedges are used mostly for corrosive liquids and non-condensing gas. This wedge type includes two pieces which is positioned between the tapered seats in the body of the Angle Valve.
Classification According to Stem
Gate valve is also classified according to the type of stem. Stem is the device which connects the disk and the hand wheel of the valve. According to the stem the valves are classified as follows:
The rising stem valve and the Non-rising stem valve
Rising stem valve: This particular stem valve includes a threaded shaft which can be rotated using a hand wheel. The stem rises when the valve is opened which helps to identify the position of the valve. When the gate valve is closed, the stem descends.
Non-rising stem valve: Another type of stem valve includes the non-rising stem valve where the stem remains stationary. There is no upward movement even when the valve is opened. It is used in underground tunnels and places where there is little or no space.
Basic Advantages of using Gate Valve
There are many benefits of using these valves as it helps to restrict the flow of water.
Bi-directional: These valves can be used in both directions. Therefore it is considered to be quite efficient in quick controlling of the flow of liquid.
Excellent sealing properties: It is widely used for its tight sealing properties. It shuts down the flow of liquid completely.
Minimum loss of pressure: Another advantage of using these valves includes the minimal loss of pressure through the valves. It therefore seldom affects the durability of the pipes and ducts.

Ball Valves – The Omnipresent Valves In Equipment

Posted on March 19, 2012 by admin

Brass Float Valve
Another type of float valve is the ball Brass Float Valve. In this application the valve does not shut off the flow of liquid, but instead seals a vent line. A ball float is held in place by a bracket which keeps it properly positioned below a vent line. When the water or other liquid rises, the ball will float up and cover the vent pipe opening. This will prevent any liquids from moving up the vent line. If the seals are working properly this application can also restrict the entrance of more liquid into the reserve tank.
A maze of pipes runs through most of the industrial installations and one thing common in all these is – Valves, the critical part of any industrial equipment used to transport fluids. Valves hold supreme position in industries like, refineries, mining, chemical, natural gas, hydropower, waste recycling to name a few.
Keeping in view various industrial requirements, different type of valve designs exist. Valves Products are preferred choice for the equipment where there is need of completely closing the flow of fluid or releasing it. Mini Ball Valve are found aplenty in industrial operations because they can endure immense pressures and temperatures and are fit to be used in rugged industrial environments.
While selecting valves for industrial operations some of the points that must be kept in mind are: the industry, the condition of operation, and the type of material that the pipes will be carrying. Chemical Industry and Offshore exploration are two industries where operations are usually carried out in very extreme conditions, both climatically and operationally. These are high risk industries where even a small malfunction in a valve can lead to extensive damage to both the industry and environment. Therefore valves used here must be able to function efficiently with minimal maintenance.
Though valves a designed to serve a common function across all industries but for each industry type the material used for manufacturing the valve is different. Operational strength, resistance against rust and low maintenance are some of the factors that play a key role in deciding valves made of which particular material will hold good. For example there are valves made of cast iron, steel, or other alloys and each of them has a particular quotient of tensile strength and thus valves made out of these materials are suitable only for particular use.

Deep Look At The Stop Valves Themself

Posted on March 13, 2012 by admin

Stop Valves
It is obvious that the industry has greatly improved our daily life. Some industrial mechanisms has been adopted in our daily life. For example, the faucet has been widely used in many houses. It is one of main types of the water Stop Valves. Actually, it has effectively shut off the water to the individual plumbing appliance without having to shut off the water to the entire house. If the water stop valve fails to work, it would cause many inconvenience to our daily life.
Stop valve is the same with the name globe valve. Its featured part is the lifting device which is a kind of stopper valve clack. Within the common conical and plain surfaces, the clack moves along the centerline of the liquid. As we know the power of the water is strong, we need to take a heavy force to stop the liquid when necessary. Or we can regard it as its shortage. Considering its medium and small pipe, the liquid with dust, intensive viscosity and easy coking is not suitable to adopt the stop Angle Valve to control. However, the benefits equal. The simple structure makes it convenient for installation and maintenance. Another advantage is that it is operated with facility. And it is better for high temperature, high pressure piping or equipment to choose the stop valve.
The regular maintenance is critical for its well operated. When a little jamming is dropped in the open position, it would cause disuse. We can open and prevent this happening by closing and opening the stop-valve regularly. What’s more, we can leave it fractionally less than fully open.
No doubt that the industry is improving our life. From the living aspects, we feel close to the industrial. Hope the wondrous stop valve would do us a great help.

Replace Bronze Angle Valve For A Toilet

Posted on March 6, 2012 by admin

Bronze Angle Valve
The water supply to a sink is provided through a flexible plastic or copper tube from an angled valve, often called an “angle stop,” Angle valves: Disk Stack style valve bodies and cage-style valve bodies.under the sink. Although the valve typically remains on and offers years of maintenance-free operation, older angle valves can develop leaks as the seals age or minerals from the water build up inside the valve. Changing the Bronze Angle Valve can stop a leak or improve water flow to the sink
1 Turn off the main water supply to the home. The main shutoff valve is near your water meter. Turn on a faucet to verify that the water is off.
2 Flush the toilet and hold down the toilet lever handle to allow as much water as possible to drain from the tank. Remove the toilet tank lid and soak up the remaining water in the tank with towels.
3 Disconnect the tank water supply hose from the top of the angle valve. Turn the connector counterclockwise with a pair of channel-lock pliers.
4 Grasp the pipe coming from the wall with a pair of pliers between the wall and the retaining nut securing the angle valve. You just want to hold this pipe still but do not crush the pipe with the pliers. Turn the retaining nut clockwise to loosen the nut from the angle valve. You’ll turn the nut clockwise because you will be looking at the nut in reverse. The nut threads to the valve, not the pipe.
5 Release the pliers from the house water pipe when the nut is loose enough to turn by hand. Finish unthreading the nut by hand and remove the angle valve. Pull the small, angled compression ring off the end of the house pipe with a pair of pliers and slide the retaining nut off the house pipe.
6 Place the new angle Drain Valve retaining nut over the house pipe with the threads of the nut facing away from the wall. Push the compression ring over the end of the house pipe with the angle portion pointing away from the wall.
7 Wrap plumber’s tape around the two sets of threads on the angle valve. Position the angle valve to the end of the house pipe and thread the retaining nut onto the valve until hand-tight. To thread the retaining nut, turn the nut counterclockwise as you will be looking at the nut in reverse. Tighten the nut another 1/2 turn with a wrench.
8 Thread the toilet tank water supply line to the angle valve until hand-tight. Turn the fitting another 1/2 turn with a wrench or pair of channel-lock pliers. Turn the valve handle clockwise to shut off the valve to prevent water going into the toilet tank.
9 Turn on the house main water supply. Go back to the toilet angle valve and slowly turn the valve handle counterclockwise to supply water to the tank. Inspect the two connections on the valve for leaks. Tighten if necessary.

Brass Compression Fittings – Types Of Check Valves

Posted on February 27, 2012 by admin

Brass Compression Fittings
In some regions of the world, Bronze Check Valve may be required by law with certain types of systems, for safety. For example, a water heater and associated plumbing use check valves to control pressure and reduce the risk of explosion. Check valves are also important components in many types of medical equipment, such as non-rebreather masks used to provide supplementary oxygen. Most plumbing systems have at least one check valve, and complicated arrangements of such valves are used for safety in chemical plants, on tankers, and in a variety of other facilities.
Swing check valve
A basic swing check valve consists of a valve body, a bonnet, and a disk that is connected to a hinge. The disk swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when upstream flow is stopped, to prevent backflow.
The disc in a Brass Compression Fittings – swing type check valve is unguided as it fully opens or closes. There are many disk and seat designs available, in order to meet the requirements of different applications. The valve allows full, unobstructed flow and automatically closes as pressure decreases. These valves are fully closed when flow reaches zero, in order to prevent backflow. Turbulence and pressure drop in the valve are very low.
Lift check valve
The seat design of a lift-check valve is similar to a globe valve. The disc is usually in the form of a piston or a ball.
Lift check valves are particularly suitable for high-pressure service where velocity of flow is high. In lift check valves, the disc is precisely guided and fits perfectly into the dashpot. Lift check valves are suitable for installation in horizontal or vertical pipe-lines with upward flow.
Flow to lift check valves must always enter below the seat. As the flow enters, the piston or ball is raised within guides from the seat by the pressure of the upward flow. When the flow stops or reverses, the piston or ball is forced onto the seat of the valve by both the backflow and gravity.

Bronze Float Angle Valve Operation Theory

Posted on February 21, 2012 by admin

Bronze Float Valve
A Bronze Angle Valve is a fluid regulating device used in plumbing and industry. It has inlet and outlet ports aligned at an angle with respect to each other, the most common angle being 90 degrees. The inlet and outlet ports can be threaded for connecting to galvanized steel and iron pipes, or they can have compression fittings for connecting to copper pipes. When an angle valve is used as a shut-off valve for residential plumbing fixtures, it is called an angle stop valve, or simply an angle stop.
Design
An angle valve is essentially an enhancement of a basic globe valve (a linear motion valve used to control fluid flow). At ordinary flow rates, pressures and temperatures, angle valves behave similarly to globe valves.
Flow
The fact that the ends of the Bronze Float Valve are at 90 degrees to each other means that its diaphragm, or membrane, can be a simple flat plate. Fluid flowing through the valve must negotiate just a single 90 degree turn and can be discharged downwardly in a controlled, symmetrical fashion.
Advantages
The design of an angle valve means it can be used not only as a control valve, but also as a physical piping elbow. The discharge from an angle valve compares favorably with other types of valves in terms of flow rate and erosion.

Replace Drain Brass Angle Valve

Posted on February 14, 2012 by admin

Brass Angle Valve
Whether you’re a weekend camper or a full-timer, there are some jobs around your RV that require immediate attention. A leaking Drain Valve on your gray water tank isn’t as dire as one on your black water tank, but you shouldn’t let either one drip. Not only is it considered rude, in some parks you can be ticketed. The drain valves, also called waste, slide or knife valves, are designed to be easily replaced on most campers.
1 Set the gas control to “pilot,” or shut off the gas supply. For an electric water heater, shut off the power at the main circuit panel.
2 Close the cold water shut-off valve. Turn on the temperature and pressure relief valve located on top of the water heater. Attach a garden hose to the drain valve, and drain the water heater. Run the hose to a floor drain or outside and before turning the drain valve on.
3 Remove the garden hose from the drain Brass Angle Valve once the water flow stops and turn the valve off. Leave the temperature and pressure relief valve open.
4 Use a wrench to remove the old drain valve. Apply pipe sealer or Teflon tape to the threads of the new drain valve, and replace. Check to ensure that the new drain valve closes once it’s in place.
5 Open a hot water faucet at any sink or tub in the house. Then turn on the cold water shut-off valve that was turned off earlier. Allow the water heater to fill. Close the temperature and pressure relief valve and the faucet when the water is running at a steady stream.
6 Check the new drain valve to make sure it’s tight, then turn on the gas supply or power to the water heater.
