Hydraulic LEDEEN Actuators
Quarter-turn and linear designs
Achieve on-off modulating control of multiple valve types.
Our DYNATORQUE SD declutchable manual overrides are used with pneumatic, hydraulic and backdrivable electric actuators. These products are sandwich mounted as part of an automated valve package to provide manual operation of the automated valve if a loss of plant air supply, power gas, hydraulic fluid power, or electricity occurs.
The declutch mechanism is designed to mount between the valve and its primary driving mechanism. The declutch locks in both the engaged and disengaged positions.
We offer a locking device for DYNATORQUE SD manual overrides to prevent engagement or disengagement
