ISOLATOR - Model 2.0 - Metal Seated Severe Service Ball Valves Brochure

The MOGAS PORV, a pneumatic actuated pressure relieving valve, prevents excessive system pressure accumulation. The set pressure of the PORV is lower than that of the spring-loaded safety valve to prevent or reduce the number of lifts of the safety valve, thus extending their life. The PORV is available either non-stamped or with the “V” stamp. The “V” stamped PORV has been flow certified by the National Board of Boiler and Pressure Vessel Inspectors.
