Introduction To Pneumatic Actuators
- Nov 03, 2016 -

Pneumatic actuator actuator and adjustment mechanism is a unified whole, its implementing agencies have thin-film type and the piston type, fork and rack and pinion type. Piston stroke length, requirements applicable to high thrust and small thin-trips, can directly drive the valve stem. Fork-type pneumatic actuator torque, small space, the torque curve is more in line with the torque characteristic curve of the valve, but I'm not very beautiful; often used in high torque on the valve. Rack and pinion actuators are simple in structure, stable and reliable, and the advantages of safe explosion-proof, power plant, chemical industry, refineries and other production processes with high security requirements in a wide range of applications.
