Selecting the appropriate safety valve type is critical for protecting pressure vessels and ensuring personnel safety. The choice depends on the medium, operating conditions, and discharge requirement

A safety valve is an automatic pressure relief device activated by inlet static pressure, standing as one of the most critical safety accessories for pressure vessels. When internal pressure exceeds a

As the ultimate protection device for pressure vessels, the installation position and method of safety valves directly impact relief effectiveness and system safety. The following four points must be

A Piston-Type Disc Spring Safety Valve, also known as an Externally Loaded Spring Safety Valve, is an advanced evolution of the conventional spring-loaded safety valve.

This advanced safety valve uses high-pressure gas instead of mechanical springs, enabling stable pressure limiting from 0.1 MPa to ultra-high pressure ranges. Its compact dual-stage design provides bo

Piston disc spring safety valves replace conventional coil springs with disc spring stacks, delivering superior pressure stability. The integrated pneumatic piston actuator enables dual-control functi

Must be installed vertically and as close as possible to the protected equipment or pipeline. If not feasible, the total pressure drop in the inlet piping must not exceed 3% of the set pressure.
