If the c o m p r e s s e d a i r s u p p l y i s suspended, enables open & close valve operation to be performed manually. C E ▲ Adjustment Mechanism for Opening Position Adjusts the opening position. ▲Special Painting Prote c t s t he ac tu ato r f rom causticity atmosphere. F G ▲Potentiometer Converts the degree of valve opening into a resistance value, which is fed back to an electrically operated positioner etc. ▲E-E Positioner Provided on valves used as control valves for temperature, flow rate, PH etc. Receives resistance value from the potentiometer. ▲Space Heater Used to prevent the actuator from freezing. @ A B ▲Output Contact Limit Switches Fitted in addition to the ordinary limit switch. Picks up the signal and actuates other operations. C For Pneumatic Actuated Valves For Electric Actuated Valves Outline of Asahi AV Valve D (Reference)
