Aluminium Alloy Pressure Vacuum Relif Valve

Explosion-proof fire breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work, equipped with fire retardant explosion-proof function.


Model QHXF-2000 is designed to vent to atmosphere to protect your tank from damage created by over-pressure or excessive vacuum.Costly product evaporation losses due to normal tank "breathing" are greatly reduced.Because it retains toxic vapous,atmospheric contamination is minimized.This helps to provide increased fire protection and safety.
