Pressure range: 150LB-2500LB
1. Compact structure, beautiful appearance, precision casting, and smooth surface.
2. The pilot operated safety valve is composed of main valve and pilot valve, with the system pressure as driving force, and the pilot valve controls the opening and closing of main valve.
3. Soft seal structure is adopted for main valve seat and valve clack so as to reach zero leakage before and after release.
4. The allowable working pressure is close to the set pressure of safety valve. Just a small overpressure can make the main valve to rapidly reach the full draining state with large discharge capacity.
5. Pilot valve is of non-flow structure, which reduces the emission of media and environmental pollution. The blowdown of pilot valve is adjustable, and the set pressure of safety valve can be tested online.
