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
