Hydraulic Ledeen Actuators
Quarter-turn and linear designs
Quarter-turn
Quarter-turn hydraulic actuators are used for on/off or modulating control of any ball, plug, or butterfly valve utilizing hydraulic actuator supply.
Linear
Linear hydraulic actuators are used for on/off or modulating control of any gate valve or rising stem ball valve utilizing a hydraulic actuator supply.
Features
- All models available as double acting or spring return
- Open and close travel stops, ± 3 degrees minimum
- Local position indication
- Suitable for SIL3 environments
