Ledeen Pneumatic/Hydraulic (LTP) Actuators

Pneumatic/Hydraulic (LTP) 'T' Series Actuator.  Operating from air or natural gas, high or low pressure (50 psi min). Employing a Pneumatic motor driving an integral hydraulic pump, developing up to 2000 psi hydraulic pressure. By use of readily adjustable relief valves the torque output is variable enabling the actuator to closely match the valve load requirement.

By varying the basic actuator frame, the capacity of the Pneumatic/Hydraulic Power Pack, and the final output pressure the optimum actuator can be selected for the specific valve application. By the addition of a hydro-pneumatic accumulator, fail-safe action can be stored in the hydraulic circuit. This fail-safe operation is reinstated automatically when the valve is returned to the operational condition.
