CRANE® Scotch Yoke Actuators

CRANE® Scotch Yoke are available as pneumatic or hydraulic actuators. These actuators can be used for on/off application and the special torque characteristic make them ideal for control applications. Scotch Yoke actuators have an increased torque range compared to Rack & Pinion actuators.

Features And Benefits

Minimum Maintenance

Low friction, long-life compound material of construction avoids any direct contact between metals minimizes the need for maintanence. The design, engineering and materials used in their construction ensure optimum performance even in the harshest environments.

Manual Override Options

A dependable manual override facility is an important part in many valve/actuator applications. Force & Torque has a variety of override options available to meet any requirement. Availabale options include open or enclosed screws in both gear reducer and declutch override gear box, as well as a number of hydraulic override solutions.

Robust yet Lightweight Design

Totally enclosed weatherproof center-body fabricated in carbon steel or ductile iron provides an excellent strength to weight ratio. The mechanism of piston and yoke has an advantageous torque output.

Technical Details


C-HPY actuators have torque outputs for spring-return models up to 110,000Nm and double-acting models up to 240,000Nm at operating pressures of 3-10 bar.
