The Q647H/Y pneumatic fixed hard sealed ball valve is equipped with a pneumatic fork type pneumatic actuator operation switch,middle flange is connected to the upper and lower valve stems with screws, and sliding bearings are installed to reduce friction,operation is labor-saving and stable.Under normal circumstances: when the pressure is low, the valve seat seal relies on the pre tightening force of the spring to make the valve seat tightly adhere to the sphere for sealing,when the pressure is high, a piston effect is formed on the valve seat, and under the pressure of the upstream medium, the valve seat presses against the sphere for sealing.Especially suitable for situations where the medium is viscous, contains particles, and has fiber properties. Widely used in industrial automatic control systems such as petroleum, chemical, teaching equipment, light industry, high-pressure equipment, pharmaceutical, paper making etc., for remote centralized control or on-site control.
Product features:
- The three-way connection forged steel fixed ball valve is a method of dividing the valve body into three parts along the section perpendicular to the axis of the valve channel at the two valve seats,entire valve is symmetrical about the center axis of the valve stem.
- It is mainly used in pipelines to cut, distribute and change the direction of medium flow.
- Its large pivot structure ensures accurate center position of the sphere under high pressure, ensuring good operational performance of the valve.
- The standard valve seat adopts a spring structure, which pushes the valve seat towards the sphere, ensuring good bidirectional sealing performance at the inlet and outlet.
- By using the built-in discharge valve, the middle chamber of the valve body can discharge outward.
- The pivot adopts an anti blow out protection structure, effectively preventing leakage.
- Low friction coefficient bearings minimize torque and facilitate valve opening and closing.
- The effective contact between the valve stem and valve body ensures superior performance of the anti-static grounding device.
- It has the advantages of excellent performance, high reliability, wide application, and reasonable price.
