The Scotch Yoke pneumatic actuator is a stroke piston-type actuator, which is suitable for the on-off or metering control of the valve with a 90°rotation angle, like ball valve, butterfly valve, etc. By filling compressed air into the cylinder, the piston is pushed to move linearly. The piston uses the piston pin and the U-shaped groove design of the shift fork to convert the linear motion of the piston into the rotary motion of the shift fork. The rotation of the shift fork drives the output shaft to rotate, thereby realizing the valve control.
According to the different types of action, it can be divided into single-acting fork-type pneumatic actuators and double-acting fork-type pneumatic actuators.

Features Of Scotch Yoke Pneumatic Actuators
The advantages of scotch yoke type pneumatic actuators include:
- Large output torque
- Easy to install and easy to maintain
- Good explosion-proof performance
- To help you control remotely
Applications Of Scotch Yoke Pneumatic Actuators
When the torque requirement is higher than 7000Nm, rack-and-pinion actuators are often not cost-effective. For this reason, when selecting pneumatic actuators, it is generally recommended to choose high-power scotch yoke pneumatic actuators, which can provide higher torque output.
Scotch yoke type pneumatic actuators are suitable for major heavy industries, such as:
- Petroleum and natural gas
- Shipbuilding industry
- Paper and pulp industry
- Energy industry
- Power generation industry
- Mining
