Pressure
relief butterfly valves are flow control devices used to control the flow of
water or any other liquid through a pipe. In this respect it is similar to a
ball valve. However, instead of using the ball as an anchor, it uses a disc
that is inserted into the center of the pipe. It is inserted through a rod disc
to connect to the actuator located outside the pipe. What really sets the
butterfly control valve ball style apart is that in whatever position it is in,
the flow pressure will decrease.
Pressure relief valve manufacturers India
are classified as quarter turn valves, and
there are many different types to choose from. The best option for you depends
on the required level of pressure and the application involved. The most
commonly used styles include the following:
·
Flexible - has flexible,
rubber seat and working pressure of 232psi.
·
High performance - features
a double eccentric design and a working pressure of 725psi.
·
Tricentric - It has a metal
seat and a working pressure of up to 1,450psi.
In
addition, pressure relief butterfly valves also vary depending on their
mounting scheme. The most common design option is the wafer style created by
