Product Description

This valve is used for power plant boilers, pressure containes, pressure and temperature reducing devices and other facilities. It serves to prevent the pressure from exceeding the highest allowable pressure value and ensured the safety of the device when working.

1. Wehn the medium pressure rises to the set pressure, the impulse safety valve will open , and the medium will enter into the piston chamber of the main safety valve from the impulse pipe to drive the piston to descend, while the valve automatically open; when the impulse safety valve closes, the disc will automatically close.
2. The sealing surface is made of Fe-Based Cr-Ni Stainless Steel by over-laying welding. Through thermal treatment, the disc has stronger resistance to wear and erosion.

1. The main Safety Valve shall be installed vertically at the highest position of the device.
2. The main safety valve shall be fastened upon the gallows, which sustains the back-seat force produced in the steam discharging process of the mains afety valve.
3. The exhause pipe shall contain a special gallows, and the steam exhaust pipe's weight shall not be exerted on the main safety valve. The connecting flange between the main safety valve and exhaust pipe shall be free of any extra prestress.
4. At the lowest point of the exhaust pipe, water drainage shall be taken into consideration to avoid producing water hammer while discharging steam.
