Overview
CRA’s Pressure Vacuum Relief Valves (PVRVs) are engineered to protect storage tanks, digesters, gas holders, and process vessels from damaging overpressure and vacuum conditions. By allowing controlled in-breathing and out-breathing, PVRVs maintain internal pressure within safe limits during filling, emptying, and thermal fluctuations. Designed for tight sealing and high flow efficiency, CRA PVRVs minimize vapor losses while ensuring long-term mechanical integrity of tanks and connected systems.
Key Benefits
Maintains tank pressure close to set points, reducing structural stress and losses.
High seat tightness minimizes vapor release and environmental impact.
Optimized internals allow large flow rates with compact valve sizing.
Stable pallet movement ensures consistent opening and reseating behavior.
Field-replaceable internals simplify inspection and maintenance.
