An Introduction To Pressure Relief Butterfly Valves

The pressure relief butterfly valve is the flow control device that is used to regulate the flow of water or other fluid through the pipe. In this case, is very similar to a ball valve. However, instead of using the ball as an anchor, it uses a disk that is inserted into the center of the pipe.

Butterfly valve pressure relief valve is classified as a quarter turn, and there are several different types to choose from. The best option for you will depend on the required level of pressure and application involved. For more information on the Butterfly valve, visit

The style of the most widely used is as follows:

o High Performance – has a double eccentric design and working pressure 725psi.

o Tricentric – has a metal chair and working pressures up to 1,450psi.

In addition, the pressure relief butterfly valve also differs depending on their placement schemes. The most common design is the selection of wafer style. 

It is reasonably priced and is designed to maintain a seal against pressure from several directions that prevent backflow in the system are only designed for one direction of flow. They use a tight-fitting seal, such as o-rings or gaskets, and flat faces on both sides of the valve.

A pressure relief butterfly valve can be used in several different applications. Firefighters use their hose to limit the pressure they create, for example. They are also often used on the front and rear suction port, water pumps, and tanks.

 In addition, to simply act as a regulator device, cast iron butterfly valves can also be used to regulate the flow of water in the pipe, which is actually able to start and stop the flow as desired. 

Control valve butterfly design is one of the most well known and appreciated is available, to be very effective in its simplistic design.
