  • Pneumatic Emergeny Cut-off control Valve descriptipon

    Pneumatic Emergeny Cut-off control Valve is widely used in pneumatic valve off petroleum, chemical, metallurgy, paper, pharmaceutical, electroplating and other industries.Pneumatic Emergeny Cut-off control Valve uses piston actuator and also can adopts GT type, AT-type pneumatic actuators, double acting and single-acting (spring return), rack and pinion, safe and reliable; Meanwhile AW series of large diameter valves using pneumatic actuator fork-type transmission , reasonable structure, large output torque, a double-acting and single-acting.The control valve body can be globe type,ball type,butterfly type as the cut-off valve body.

    Pneumatic Emergeny Cut-off control Valve feature
    1, gear dual-piston, the output torque, small size; 
    2, the choice of aluminum alloy cylinder material, light weight, beautiful appearance; 
    3, at the top, bottom mounting manual operating mechanism; 
    4, rack connection opening angle can be adjusted, the rated flow; 
    5, the actuator feedback signal indicating an optional live and various annexes to automate operations; 
    6, IS05211 standard provides a convenient connection to install the replacement product; 
    7, both ends of the adjusting screw allows the sections of standard products at 0 ° and 90 °, with an adjustable range of ± 4 °. To ensure the accuracy of synchronization with the valve.
