Pressure/Vacuum Relief Valve (PV Valve) · PV Valves & Vent Systems
It is normally installed in cargo tanks, pump rooms, deck manifolds, cargo heating circuits or cargo vent systems depending on the component. Its primary duty is to control, transfer, strip, heat or safely vent tanker cargo while maintaining containment and operational control. In service it interfaces with cargo piping, valves, tank instrumentation, hydraulic/electric drives, stripping lines, heating medium, ESD functions and cargo control systems. For exact limits, settings, test values and approved maintenance criteria, refer to the manufacturer documentation for the exact figure.
