Pneumatic trunnion-mounted ball valve
Reliable sealing: Even when the sealing surface is worn, it can ensure good sealing performance.
Fireproof structure: equipped with a fireproof sealing ring to prevent the sealing ring from burning out due to sudden heat or fire.
Automatic pressure relief: When the pressure of the stagnant medium in the valve chamber abnormally increases beyond the pre tension force of the spring, the valve seat will automatically release pressure and reset automatically after pressure relief.
Easy maintenance: The ball valve has a simple structure, and the sealing ring is generally movable, making it easy to disassemble and replace
