Product Introduction
Description
The Autorun Scotch yoke pneumatic actuator is a heavy-duty pneumatic actuator designed for large valves. It can be classified into two types based on the action: single-acting and double-acting. The model listed here is of the double-acting type. The actuator's switching action is carried out through the drive of an air source. Single-acting type is also available.
Features
• Large torque, Wear & Corrosion resistance, Manual override options.
• ISO 5211 mounting pattern, Robust yet light weight design.
• Female double square output drive
• Namur mounting pad for direct mount solenoid valves
• Standard VDI/VDE 3845 mounting for top mount accessories
• High cycle life with low friction bearings on all moving and sliding surfaces

Specfications
Air supply: 3 bar~6bar;Travel Adjustment: 90° ± 5°;Operating temperature: -20 ~ +80° C;Type: Double acting
Optional accessories: Manual override, Limit switch box, Solenoid valve, Electro-pneumatic positioner, Air regulator
Application: Either indoor or outdoor
Operation
Compressed air is introduced into the cylinder, exerting pressure on the piston to generate linear motion. The piston, connected to the fork with a U-shaped groove design, converts this linear motion into rotary motion of the yoke. The rotation of the yoke, in turn, drives the output shaft to rotate, enabling precise control of the valve.
