1" BSP Safety Relief Valve

The 1" BSP Safety Relief Valve (DN25) is designed to protect tank trucks, tank containers and process installations against dangerous overpressure and vacuum. The valve automatically opens when the preset pressure or vacuum value is reached and closes again once the pressure has returned to normal. This prevents damage to the tank and installation while ensuring safety during transport, loading and unloading operations.

This safety relief valve is manufactured from high-quality 316 stainless steel (SS 316) and is suitable for applications in the chemical industry, food industry, ADR transport and other demanding industrial environments. Each valve is individually tested and supplied with a pressure test certificate for optimum reliability.
