 Analyze the application to determine which valve is best suited for installations, keeping in mind the service for which the valve is recommended. Before installing the correct valve, review the installation instructions to prevent damage to the valve and to assure its maximum efficiency. 1.Cut tube end square. Ream, burr and size. 2.Use sand clot...

Approximately 25 paintings from the permanent collection at the Georgia Museum of Art appear to have been compromised to varying extents by moisture created when an HVAC valve failed in a storage room. The problem was discovered Sunday morning, Jan. 4, about 10 a.m. when a security supervisor making a routine check noticed elevated humidity in one of the ...

Although many different types of valves are used to control the flow of fluids, the basic valve types can be divided into two general groups: stop valves and check valves. Besides the basic types of valves, many special valves, which cannot really be classified as either stop valves or check valves, are found in the engineering spaces. Many of these valve...

In certain fluid power systems, the supply of fluid to a subsystem must be from more than one source to meet system requirements. In some systems an emergency system is provided as a source of pressure in the event of normal system failure. The emergency system will usually actuate only essential components. The main purpose of the shuttle valve is to iso...

A Gate Valve, or Sluice Valve, as it is sometimes known, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. They are so-named because the part that either stops or allows flow through the valve acts somewhat like a gate. The gate is usually wedge-shaped. When the valve is wide open the gate is fully drawn up i...

In fact a counterbalance valve is an improved pilot operated check valve. An important and major difference between these two valves is: - the opening pressure of a pilot operated check valve depends on the pressure (applied by the load) behind the valve; - the opening pressure of a counterbalance valve depends on the spring pressure behind the valve. The...

Have you ever taken a shower that was perfectly adjusted for the right temperature, only to have someone somewhere else in the house turn on a tap or flush the toilet and completely mess up your perfect temperature shower? If you have, you may wish to head to your local plumbing supplier and inquire about a pressure balance valve. The most common challen...

A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve guide. In most applications a pressure differential helps to seal the valve and in some applications also open it.  Poppet valves ...

A throttle valve is a device installed in the fuel systems of engines which regulates the pre-determined amounts of fuel and air which reach the combustion areas of the engines. The amount of fuel and air that goes into the combustion chamber regulates the engine speed and, therefore, engine power. In a fuel-injection engine, it is part of the metering de...
