Product Description

Stainless Steel Flanged Vacuum Pressure Relief Vent Valve

Product Description

 

Vacuum negative pressure safety valves are divided into two categories: spring type and rod type. In addition, there are impulse safety valves, pilot safety valves, safety switching valves, safety relief valves, static weight safety valves, etc.

Application

 A72W-10P/R vacuum negative pressure safety valve is suitable for negative pressure systems with temperatures ≤ 200 ºC. When the negative pressure inside the container exceeds the allowable value, the vacuum negative pressure safety valve automatically opens to inhale air; When the negative pressure inside the container reaches the allowable value, the A72W-10P/R vacuum negative pressure safety valve automatically closes to protect the equipment and system. This product is generally installed in a normal non negative pressure system. When the release valve of the container and system is not opened and negative pressure is generated, the vacuum negative pressure safety valve will automatically open to protect the equipment from damage.
