OPW Pressure Vacuum (PV) Valve for Vent Pipe
PRODUCT DETAILS
Model: OPW Vent-Line PV Valve | Application: Petroleum Storage Tank Venting
Description:
The OPW Pressure Vacuum (PV) Valve is a safety-critical component designed for use on vent pipes of underground and aboveground petroleum storage tanks. It controls the internal pressure and vacuum levels within the tank by allowing air to enter or escape when preset pressure or vacuum thresholds are reached, helping to prevent evaporation loss, over-pressurization, and vacuum damage.
Made from high-grade, fuel-compatible materials, this valve is factory-calibrated to open at specific pressure/vacuum settings, ensuring the tank remains within safe operating limits. It also acts as a flame arrestor to prevent flame propagation into the tank through the vent line, offering additional protection in hazardous environments.
