High pressure ball valve product features

    High-pressure ball valve is suitable for pipelines of Class 900～4500LB, working temperature of -28～650°C in various working conditions such as petroleum, chemical, thermal power stations, etc. The design of safety and harsh environment is specially considered. : Corrosive and strong oxidizing medium such as water, steam, oil, nitric acid, acetic acid and urea. The operation modes are: manual, pneumatic, electric, hydraulic and gas-liquid linkage.
Main features of high pressure ball valve：
1、 When the pressure of the stagnation of the high-pressure ball valve of the American standard exceeds the pre-tightening force of the spring, the valve seat retreats away from the ball to achieve the effect of automatic pressure relief. The valve seat is automatically reset after the pressure is released.
2、 In the event of a fire or a burning or softening of the seat seal due to abnormal temperature rise, under the action of the spring and the medium pressure, the spherical surface of the support ring and the sphere form a metal-to-metal contact, which achieves a temporary sealing effect and prevents The fire has been further expanded to comply with API6FA regulations.
3、The packing of the high pressure ball valve is sealed with PTFR packing and 0-ring sealing ring. It is especially suitable for gas medium. The packing is installed in the packing plate. The new SF type self-lubricating sliding bushing with low friction system can be used at any time. , reduce the operating torque.
    The high pressure ball valve has a motion of 90 degrees of rotation, the body of the plug is a sphere, with a circular through hole or passage through its axis. The ball valve is mainly used to cut, distribute and change the flow direction of the medium in the pipeline. The high pressure ball valve only needs to be rotated 90 degrees and the torque can be closed tightly. Ball valves are best suited for use as switching and shut-off valves, but recent developments have designed ball valves to throt and control flow.
