Gear operated Trunnion Mounted Ball Valve

This series of mounted ball valve are mainly used to truncate and get through the medium in the pipeline. The body of this ball valve is supported by the upper and lower fixed shaft or fixed plate. The valve seat adopts spring. So, this valve has lower torque and excellent seal feature. Furthermore, valve seat of the ball valve has varied seal materials and choose different materials of valve seat based on the medium’s temperature (seal of soft valve seat to metal ball or metal valve seat to the body of ball valve) in summary, this product has extensive temperature using range. This series of mounted ball valves are mainly used industry area of petroleum, natural gas, petrochemical, chemical, electric power plant, and mineral etc.
