P255 | High Capacity Relief Valve
BelGAS Regulators
The BelGAS P255 High Capacity Relief Valve is designed to protect gas pressure systems by safely discharging excess pressure before it can damage equipment or compromise safety. Built for use with BelGAS and other industry regulators, the P255 serves as a critical safeguard in pressure control systems.
Engineered for reliability, the P255 delivers near-zero leakage up to 98% of set pressure and maintains tight control with a ±5% set pressure tolerance. The valve reseals at approximately 92% of set pressure, ensuring consistent system protection without unnecessary gas loss.
Constructed from durable materials including CDA360 brass body components, a 302 stainless steel spring, and a nitrile seal, the P255 is built for long service life in demanding environments. It is available in 3/4″ and 1″ NPT sizes with multiple set pressure options ranging from 50 to 150 PSIG, providing flexibility across a wide range of applications.
Typical Applications:
Gas pressure regulation systems, overpressure protection, industrial gas distribution, fuel gas systems, regulator protection, commercial and industrial gas service
