Safety Relief Valves V7713 / V7715

Vanaz V7713 / V7715 Safety Relief Valve

The Vanaz V7713 (1/2-inch size) and V7715 (3/4-inch size) are spring-loaded safety relief valves, identical in specification and differing only in end-connection size. Both stay closed during normal operation and automatically open to vent gas once line pressure rises to the preset limit, closing again once pressure drops back below the set point. Fitted with a metal-to-metal seat, they are built for high-pressure applications with a 20-200 kg/cm2 set-pressure range and are suitable for CNG, LPG, CO2, nitrogen and argon service, protecting pressure-reducing systems, gas trains and pipelines from overpressure.
