Trunnion Mounted Ball Valve

Trunnion ball valve, it is a new generation of high-performance ball valves. Ball is fixed and valve seat is movable. During working, the medium pressure pushes the valve seat to closely adhere to the ball to achieve sealing. The ball is opened and closed by rotating stem. The trunnion structure ensures that the ball is subjected to uniform force. Each valve has two seats and can seal in all directions. Therefore, there is no flow direction restriction during installation, and bidirectional sealing can be achieved. This valve is generally installed horizontally. Its advantages include reliable sealing, stable sealing performance, strong pressure-bearing capacity, small opening and closing torque, long service life, and suitability for high-pressure and large-diameter working conditions. Therefore, it is widely used in high-pressure pipeline systems of petroleum, natural gas, chemical industry, etc., and is also suitable for working conditions that require long-term stable sealing.
