PV High‑Speed Vent Valve Stainless Steel Pressure Vacuum Valve for Marine Cargo Tanks

The PV High‑Speed Vent Valve is engineered for safe and efficient pressure control in marine cargo tanks. Manufactured from stainless steel, it provides durability, corrosion resistance, and long service life under harsh marine conditions.

This valve automatically regulates pressure and vacuum during loading, sailing, ballasting, and unloading, preventing over‑pressure or vacuum damage without manual intervention. When cargo tank pressure exceeds the set limit, the valve opens to release gas, maintaining balance. In vacuum conditions, it allows controlled air intake to stabilize the tank.

Equipped with fire‑safe features, the valve extinguishes sparks through high‑speed airflow or integrated flame arrestors, ensuring explosion protection. Its compact design and flange connection make installation simple, while strict material selection and precision manufacturing guarantee reliable performance. Certified by CCS, ABS, DNV, GL, LR, NK, and BV, this valve meets international marine standards, making it a trusted solution for shipbuilders, operators, and offshore engineering projects.
