DIAPHRAGM VALVE
Introduction
A Diaphragm Type Shutoff Valve is a valve designed to stop or regulate the flow of gases or liquids using a flexible diaphragm that presses against a seat to create a seal. It is widely used in gas distribution systems, high-purity gas applications, and industrial gas panels
