A46F/H/Y Pilot-operated Pressure Relief valve

A46F/C Type Pilot-operated pressure relief valve Model: A46C/A46F; Diameter: 2~8" Medium: Gas such as steam, Natural gas and Crude oil etc. pilot safety valve is a main valve and pilot valve a novel structure of the safety valve, pilot valve response system media pressure our own actions so as to control the switching of the main valve.

A46H/FPilot Operated Safety Valve structural features:
1, the seat of soft seal to ensure a good seal around the safety valve take-off
2, allowable working pressure close to the safety valve setting safety valve main valve pressure.
3, the smaller overpressure will be able to quickly reach the status of all Kai
4, the safety valve performance and the opening height from the back pressure.
5, opening and closing Adjustable differential pressure
6, the pilot valve flow structure designed to reduce emissions of harmful media and environmental pollution.

The design and manufacture standard ofA46H/F Pilot Operated Safety Valve:
structural length standard: GB/T12221-2005
connection flange standard: GB/T9113
