Hydraulic actuator Selcon

linearhandlingcontrol

The SelCon is a self-contained, electrohydraulic linear actuator with a spring-assisted trip function. It operates, for example, a valve that regulates the mass flow in a prime mover or a driven machine. Typical machines are gas turbines, steam turbines or compressors. The SelCon provides you with highly dynamic and precise control of the mass flow. This innovative actuator is a reliable plug-and-play solution with fail-safe function. The SelCon is a compact design, provides high force density and is a true alternative to conventional actuators. With the SelCon you don't need an additional hydraulic power pack with an oil tank, control block and pipework. The amount of hydraulic fluid in the system is minimal. On the outside the SelCon only has electrical and mechanical interfaces. Handling and system integration is extremely simple. No knowledge of hydraulics is required for installation and commissioning. Our engineers selected proven components when designing the SelCon. The core components consist of a servo motor, a Voith internal gear pump, a cylinder with an internal return spring and a displace­ment transducer. A control unit with implemented application software acts as the brain of the system. The actuator exhibits a high degree of operational safety and reliability; the estimated mean time between failures (MTBF) is 35 years.
