Automatic Pilot Operated Safety Valve

Product Overview

Cast Steel And Stainless Steel Automatic Pilot Operated Safety Valve

Pilot operated safety valve is a type of non direct load safety valve composed of a main valve and a pilot valve (also known as a "secondary valve"). The main valve is driven by the medium discharged from the pilot valve. Due to the pulse form of pressure in the system, it is also known as a "pulse safety valve".

This automatic valve category is mainly used on boilers, pressure vessels, and pipelines to control pressure not exceeding specified values, providing important protection for personal safety and equipment operation.
