Fork pneumatic actuators

Fork pneumatic actuator


fork type pneumatic actuators is one of the actuator is common, it is a kind of Angle of stroke piston actuator, usually applies to 90 ° Angle valves ( Like a ball valve, butterfly and plug valves) The switch to cut off the control and measurement. It is the structure of the single qigong double piston - Variable torque fork type pneumatic actuators.


the working principle of





fork pneumatic actuator


compressed air into the cylinder, drive the fork type piston movement, through the fork to the linear motion of the piston into the rotation of the disc movement, disk drives the output shaft rotation, so as to realize the control of the valve.


the gear rack type pneumatic actuator


compressed air into the cylinder, drive rack piston linear movement, rack and pinion shaft gear mesh on the driven gear shaft rotation movement so as to realize the control of the valve.


movement characteristics


fork type pneumatic actuator


working fork type pneumatic actuators, the piston movement process, the fork dish and self-lubrication rotation for the rolling friction between pin and fork dish and rotation is not affected by the wear between pin and the drive is the friction power is smaller.


the gear rack type pneumatic actuator


the gear rack type actuator for tooth jewels parallel structure, the piston movement process, the rack for sliding friction between the friction resistance is big, rack and easy to wear.
