Introduction
Cast steel trunnion mounted ball valves feature fixed ball and floating seat rings, which have two-piece and three-piece bolted bonnet structure.
The force on the ball, which is generated by the upstream fluid pressure, is all transmitted to the bearing, and the ball will not move to the valve seat, so the valve seat will not bear excessive pressure,ensuring that the sealing performance is stable and the service life is long.
Features
1.Labor-saving operation as the ball is supported by dual bearings to reduce friction;
2.PTFE unisexual material sealing ring is embedded in the stainless steel valve seat, and the end of the metal valve seat is equipped with a spring to ensure sufficient pre-tightening force of the sealing ring;
3.Fireproof sealing ring is set between the ball and the valve seat to form a metal-to-metal seal in case of fire according to AP16FA and API607 standards;
4.When the pressure of the stagnant medium in the valve cavity rises abnormally and exceeds the pre-load of the spring, the valve seat retreats away from the ball to achieve the effect of automatic pressure relief;
5.Drain holes are set up and down the valve body to check whether the valve seat is leaking.
