PV Valve DN80 SS316L Marine

Tanktech PV Valve DN80 SS316L Marine — PV Valves & Vent Systems. The supplied category identifies the equipment as Pressure/Vacuum Relief Valve (PV Valve), and it is normally installed on the cargo-tank vent system or vent riser where tank pressure and vacuum are relieved to protect the tank structure. In that listed role, its primary purpose is to open automatically when tank pressure or vacuum reaches the approved operating threshold and reseat when conditions normalize. Compared with a normal isolation valve, a PV valve is a calibrated protective device whose seating, freedom of movement and approved set point are safety-critical. Within the supplied list, neighbouring variants are distinguished by their model designations and naming, while the source does not state further model-specific hardware differences. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
