Pneumatic ball valve switch consist of high accuracy pneumatic actuator and precision casting ball valve. Mainly divided into pneumatic soft sealing ball valves and pneumatic metal sealed ball valve two types. Pneumatic switch ball valve has a compact structure, small volume, reliable operation, low coefficient of flow resistance, good sealing, easy maintenance, easy installation, strong adaptability, etc.
Pneumatic ball valve can realize on-off when matched with moving limit switch, solenoid valve, pressure reducing valve, and 0.4 0.7 MPa gas source. And output two passive contact signal to control valve on or off. Pneumatic type O shape ball valve is particularly suitable for medium which is viscous, containing particles and fiber properties. Pneumatic switch ball valve is widely used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, pharmaceutical, paper and other industrial automatic control system, as long-distance centralized control or local control system.
AT pneumatic actuator
Gear rack Dual-piston is symmetrical, quick action and stable. High accuracy, big power output. Can realize reversed direction revolving by simple changing the piston position.
Aluminum alloy cylinder.
All the double action and single action actuators have the same cylinder and side cover.
Complex type conform to safety spring group, convenient to increase or decrease spring number.
Two separate bolts at two side, convenient regulating valve ON or OFF position. Lengthening the bolt if need all travel regulating.
Multifunction position indicator, local showing, conform to standard VID/VIE3845, NAMUR, can install and output all the accessories like limit switch box, electric positioner, location transducer.
Air source port conform to NAMUR standard, and install NAMUR standard solenoid valve directly.
Composite bearing, piston leading ring and Output shaft bearing at Gear back side is rubbing protection of metal to metal, long service life.
All fixing material is stainless steel, anticorrosive.
