Features:
  1. Adopts rack and piston double piston symmetrical structure, which enables fast and steady action, high precision, high output power.
  2. The cylinder enables its longer service life and low friction coefficient.
  3. Both double acting actuators and single acting actuators have same cylinder and ends cap, which makes it convient for changling action mode.
  4. Adopts conbined preload safe spring, which is safe and covenient for assembling or removing springs.
  5. It enables installall accessories, such as the limit switch box, electric positioner and position sensor.
  6. All fasteners are made of stainless steel, which enables long-term corrosion resistance.
  7. The connection parts are in line with new international standards ISO5211 and DIN3337(F03-F25).
Working Principle:
Operating Principle of DR Double-action Model
When the air supply pressure enters the medium chamber between two pistons ol the cylinder from the gas port (2), it will make two pistons separated and moving toward both ends of the cylinder respectively; the air in the air chamber at both ends will be disch-arged from the gas port (4), and two piston racks will drive the out-put shaft (gear) to rotate counterclockwise. On the contrary, when the air supply pressure enters the air chamber at both ends from the gas port (4). A will make two pistons move toward middle of the cylinder; the air in the medium chamber will be discharged from the gas port (2). and two piston racks will drive the output shaft (gear) to rotate clockwise (if the piston is fixed in opposite direction, the output shaft will rotate reversely, and it will become double -action reverse-rotation DL model.

Operating Principle of SC(SO)Single-action Model
When the air supply pressure enters the medium chamber between two pistons of the cylinder, it will make two pistons separated and move toward both ends of the cylinder and compress springs at both ends; the air in the air chamber at both ends will be discharged from the gas port (4); two piston racks will drive the output shaft (gear) to rotate counterclockwise. When the air supply pressure is commutated by the solenoid valve, two pistons of the cylinder will move towards the middle pari, under the pressure of springs, and the air in the medium chamber will be discharged from the air port (2); two piston racks will drive the output shaft (gear) to rotate clockwise (if the piston is fixed in opposite direction, the output shaft will rotate in the opposite direction when the spring is reset, and it will become single-action reverse-rotation SO model.
