Choose by motion job

Start with the motion the actuator must make.

Pick the closest actuator use case, then confirm bore, stroke, load, mounting, pressure, speed, and space constraints before RFQ.

Scenario 01

Drive a ball valve or butterfly valve.

Valve actuation starts with required torque, rotation angle, duty cycle, and mounting interface.

Category FAQ

Common questions before sending an inquiry.

01Pneumatic Rotary ActuatorsHow do I select torque for a pneumatic rotary actuator?

Start with the load, lever arm, inertia, motion angle, acceleration, and available air pressure, then include a suitable safety margin.

02Pneumatic Rotary ActuatorsWhat is the difference between rack-and-pinion and vane rotary actuators?

Rack-and-pinion actuators are often chosen for stronger torque and robust output. Vane actuators are compact and smooth for lighter angular motion.

03Pneumatic Rotary ActuatorsWhat details help with a rotary actuator replacement?

Send model code, photos, output shaft dimensions, angle, torque or load, mounting holes, port size, and sensor or stop adjustment details.
