Ledeen actuator Gas Over Oil LTF/Q
For natural gas applications where the pipeline medium is used to power the actuator via gas over oil tanks. These gas/oil tanks containing hydraulic fluid, are arranged to accept filtered gas via a suitable control system. The gas, at line pressure, acts upon the hydraulic fluid power to drive the previously described Scoth-yoke mechanism.
The torque output of this type of actuator varies with the line pressure available as does the torque requirement of the main line valve. In all other respects the gas/oil units are identical to the previously described units and all accessories such as limit switches, limit valves etc. can be applied.
