The Bulgin® Safety Relief Valve is designed to provide overpressure protection in compatible gas systems, helping protect downstream equipment from excessive pressure.
Manufactured with a chrome-plated brass body, the valve features a set pressure range of 16–26 bar (1,600–2,600 kPa) and is designed for reliable pressure relief and resealing performance.
Each valve is factory tested for correct set pressure and resealing performance, with additional proof and burst testing to support dependable operation in industrial gas applications.
Key Features
Set pressure range of 16–26 bar (1,600–2,600 kPa)
Chrome-plated brass construction
Designed for gas pressure relief applications
1/4" NPT male inlet
1/4" NPT female vent port
Factory tested for correct set pressure and resealing performance
Proof and burst tested
Bubble-tight sealing performance
Standard Viton® (FKM) seal
Optional Kalrez® (FFKM) seal configuration
Compact design for integration into gas control equipment
Pressure Relief Protection
The Bulgin Safety Relief Valve is designed to relieve excess pressure when the system reaches the valve's specified set pressure.
Once system pressure decreases sufficiently, the valve is designed to reseal, helping maintain pressure integrity during normal operation.
The 16–26 bar set pressure range allows the appropriate valve configuration to be selected according to the pressure protection requirements of the gas system.
Typical Applications
Gas pressure regulation systems
Gas distribution equipment
Industrial gas control panels
Laboratory gas systems
Pressure control assemblies
Equipment overpressure protection

Designed for Reliable Pressure Protection
The combination of chrome-plated brass construction, factory-tested relief performance and bubble-tight sealing makes the Bulgin Safety Relief Valve a practical component for gas control and distribution systems.
With a choice of seal materials and a 16–26 bar set pressure range, the valve can be specified to suit compatible gas equipment and operating requirements.
Note: The relief valve must be selected with a set pressure appropriate for the protected equipment and system design. Confirm gas compatibility, seal material, required relief capacity and venting arrangements before installation. The valve's set pressure must not exceed the allowable pressure of the equipment being protected.
