| Electro-hydraulic pilot actuator for activation of pilot valves, inclusive position controller for hydraulically actuated final cylinder.
Application
Closed-loop control of control valves on turbo-machinery by actuating upstream connected pilot valve.
Design
Voith pilot actuator with controller is the intelligent and compact electro-hydraulic combination of Voith control magnet-VRM with integrated position controller for closed-loop control of clients superior final hydraulic cylinder, hydraulic flow controller and pilot hydraulic cylinder. Advantages
- Precise, dynamic and virtually hysteresis-free actuation of pilot valve
- Increased reliability due to mechanical stroke feed back instead of electrical pick-up
- Integrated position controller for superior final cylinder, external complexity becomes not applicable - Plug and Play
- Dirt-insensitive, temperature-independent and robust design
- Fail safe by integrated restoring spring
- Explosion-proof design also possible
