Actuator Scotch Yoke

Valve actuator scotch yoke type are 90˚ driving mechanisms that can be powered by compressed air or hydraulic oil from an external source to converts linear motion of a bar sliding back and forth into a rotational motion. Rotary actuator scotch yoke are designed to turn heavy loads and provide high torque output. A valve usually requires a higher torque on the start and the end of its stroke.Scotch yoke actuator is an ideal device to meet this request.

Housing Module

1. High-rigidity one-piece cast housing

2. Dual guide rod design for the entire series, optimizing lateral loads

3. Two types of scotch and yoke designs: symmetric type and canted type

4. Base connection plate conforms to ISO 5211 standard, facilitating direct installation.

5. Adjustable travel limit devices for 0° and 90° to avoid valve overtravel

6. Self-lubricating oil-free bearing design with low friction and long service life.

Cylinder Module

1. Three-stage precision grinding process and hard chrome plated cylinder provide wear-resistant and corrosion-resistant properties, as well as excellent low-friction coefficient and reliable sealing with mirror-grade roughness.

2. Seal ring and wear-resistant ring dual-guided design ensures excellent dynamic sealing performance.

3. Self-lubricating, oil-free bearing design at piston rod minimizes friction and extends service life.

4. Multiple air source interface sizes are available

Spring Module

1. Fully enclosed welded anti-misoperation design to ensure safe use

2. High-quality supplier provided springs with guaranteed performance

3. Corrosion-resistant resin coating on the surface of the spring

4. Full-stroke guide for the spring seat to achieve smooth operation

5. Embedded screw and hydraulic manual design to reduce product length and facilitate installation.
