Compact Ledeen Actuators
Save valuable rig space
Compact Ledeen HS and CP actuators—some of the smallest actuators available on the market—save valuable space on a production platform or FPSO vessel when installing automated valve packages within the piping system.
Ideal solutions for space-constrained installations
Unlike conventional scotch yoke actuators, compact Ledeen actuator profiles are concentric with the valve stem, reducing the required installation space and enabling alternative piping options.
Application-specific torque mechanism
Ledeen actuators have two different torque mechanisms available, enabling the most appropriate mechanism to be utilized for maximum efficiency.
- High-pressure hydraulic applications: A small helical spline mechanism is used with a small piston diameter to generate high torque outputs.
- Low-pressure pneumatic applications: The larger helical slot mechanism is combined with a larger piston diameter to generate an equivalent torque output.
Independently adjustable travel stops
For precise valve positioning, the actuators feature a patent-pending integrated adjustable travel stop subassembly. Valves can be accurately set to the closed position to ensure positive shut-off and set fully open to optimized process flow.
