3PC black ball

Ball: pneumatic valve three-piece ball valve pneumatic actuator configuration composed into a double-acting pneumatic actuators and single-acting, through the solenoid valve control, valve switching. Pneumatic valve can achieve intelligent control, fast turn on or off the pipeline, to be able to effectively control and manage the network. Pneumatic valve having a rotary output torque, open fast, smooth and reliable. Butterfly structure can be divided into bias plate, vertical plate, swash plate and leveraged. Butterfly press seal seal type can be divided into soft and hard seal two. Soft sealing butterfly valve commonly used rubber ring seal, seal butterfly valve commonly used metal ring seal. Press connection type can be divided flange connections and clamp connections; can be divided according to the manual transmission, gear transmission, pneumatic, hydraulic and electric several.
