Pneumatic valve hian compressed air chu power source atan a hmang a, cylinder chu actuator atan a hmang bawk. Electric valve positioner, converter, solenoid valve, position holding valve leh accessories dangte kaltlangin ON{{1} off emaw proportional adjustment emaw tih theihna turin valve chu a khalh a, industrial automation control system atanga control signal chu pipeline medium: flow, pressure, temperature leh process parameter dang regulation tihfel nan a dawng bawk. Pneumatic valve hian simple control, fast response, intrinsic safety leh additional explosion-proof measures te characteristic a nei a.
Pneumatic valve hi a tlangpuiin pneumatic actuator leh control valve connected, install leh debug a ni. Pneumatic actuator hi single acting leh double acting ah te then theih a ni.
