Gas-Over-Oil LEDEEN Actuators

Consistent engineering design and efficient modularity

Quarter-turn

Quarter-turn gas-over-oil actuators are used for on/off control of any natural gas transmission ball or plug valve utilizing a high-pressure natural gas or nitrogen actuator supply.

Linear

Linear gas-over-oil actuators are used for on/off control of any natural gas transmission gate valve utilizing a high-pressure natural gas or nitrogen actuator supply.

Features

All models available as double acting
Open and close travel stops, ±3° minimum
ASME/PED gas-over-oil pressure vessels with dipstick, filter, and adjustable speed controls
Suitable for SIL3 environments
