¡ô Double action actuator: open and close the valve
¡ô Single action actuator(Spring return):When air or power is lost, the actuator either closes the valve automatically (often-closed style) or opens the valve automatically (often-open style)
¡ô Double-control solenoid valve: power to one solenoid opens the valve, power to the other solenoid closes the valve. This kind of solenoid possesses the memorial function(available for explosion proof)
¡ô Single-control solenoid valve:power to the solenoid opens or closes the valve. Loss of power will close or open the valve(available for explosion proof)
¡ô Limit switch box(signal feedback):remotely passes the signal of the valve¡¯s opened and closed status(available for explosion proof)
¡ô Pneumatic positioner: according to the air pressure(0.2¡«1bar)to control the medium flux(available for explosion proof)
¡ô Electric positioner: according to the electric current(4¡«20mA)to control the medium flux(available for explosion proof)
¡ô Electric-pneumatic transfer: transfers the current signal to air pressure signal for compatibility with positioner
¡ô Tri-unit Air disposal: this includes regulator, filter and oil unit. They can clean and lubricate the connection parts
¡ô Manual equipment: Able to use manual operation in the event of loss of air or power |
