F3 series pneumatic actuator consists of two types, namely the double-acting and single-acting (spring return). It is composed

It is composed of two separated cylinders, double pistons, and scotch yoke-type driving mechanism, facilitating manufacture of large-size cylinder body. The product features high output torque and flexible and steady actions. 

The inner wall of the cylinder body and piston axles has been plated with hard chrome, ideal in resisting abrasion.

All the sliding parts have been equipped with oil-less bearing and pilot ring to minimize coefficient of friction and prolong the service life. The output torque characteristic of U-curve for the F3 series pneumatic actuator is more suitable to large-diameter ball valve and butterfly valve in terms of switch on/off and regulation; meanwhile, it is also fit for other occasions of 90°rotation.
