Vacuum pressure relief valve HV-PVRV-06

for tankslow-pressurefor the chemical industry

A Breather Valve (Pressure Vacuum Relief Valve – PVRV) is designed to protect storage tanks and process vessels from excessive pressure and vacuum during filling, emptying, and thermal changes. It automatically relieves excess vapor pressure and admits air or gas when vacuum develops, helping prevent vessel rupture, buckling, and product losses.

The straight-pattern design with screwed end connection provides a compact and economical solution for smaller tanks and low-pressure vapor applications.
