Wafer Type Butterfly Valve Operating Process:

A quarter-turn valve called a wafer type butterfly valve is made to control or separate the flow of liquids and gases in industrial piping systems. For reliable flow control, its small wafer body is placed in between two pipeline flanges, giving a lightweight and space-saving option.

A 90-degree twist opens or closes the spinning disc, allowing for smooth operation and low operating torque. It is a sensible option for many industrial uses because to its compact size, regular sealing efficiency, and simple installation.
