♦ Outline size drawing and size data:  ♦ Double acting pneuamtic actuator:     ♦ Double acting working principle:
  When air pressure from the port (2) into two piston cylinder between central cavity, make the twoends to the cylinder piston separation direction, both end air cavity air through the port (4) discharge, and at the same time, make the two piston rack synchronous drive the output shaft (gear) counter-clockwise. And air pressure from the port (4) into the cylinder ends air cavity, two pistons to cylinder intermediate direction, and the middle gas cavity air through the port (2) discharge, and at the sametime, make the two piston rack synchronous drive the output shaft (gear) clockwise.   (if the piston relative inverse direction installation, output shaft that into reverse rotation)    ♦ About us:   Thank you very much for your checking here, we are specially provide kinds of automatic control system butterfly valves, ball valves, solenoid valves, angle seat valves, etc, and such as PODF/ POSF Powder butterfly valve has been widey used in  petroleum, metallurgy, electric power, steel, chemical industry, water treatment, bio-pharmaceutical, paper making, foodstuff, military industry and other fields; Any intersting in ur product please feel free to keep in touch, many thanks;  Arina, Polovo valves, Shanghai
