The two piece trunnion ball valve consist a valve body and a bonnet, benefits from its two pieces body structure, there is no friction when open and close, which totally solves the problem of the leak-profess causing form friction between the sealing surfaces in traditional valve. People can check and repair the valve assembled on the pipe directly, which can reduce the number of stopping car for the purpose of installing, which finally lower the cost.
Thus the two piece trunnion ball valve is often preferred as it has a distinctive lower operating torque than the floating ball valve since pressure forces tending to push the ball downstream are supported by a trunnion rather than the valve seat. The valves are mainly used in chemical engineering, petroleum, natural gas, metallurgy industries.
