Linear Electro-hydraulic Actuator for Steam Turbines, Gas Turbines and other Applications A Voith control servo motor is a linear electro-hydraulic actuator. It operates a valve that controls the mass flow needed to drive machinery. Voith servo motors ensure very precise and high dynamic control of the mass flow. The control servo motor is an intelligent and compact functional unit consisting of a hydraulic cylinder, control magnet with integral position control, hydraulic pilot valve and position sensor. When a servo motor is used, no additional components such as pilot valve and hydraulic cylinder, for instance, are needed to operate the control valves. A standard 4 – 20 mA signal specifies the position of the piston rod. The control servo motors feature a simple and compact design. This ensures con­sist­ent and reliable operation. The Mean Time Between Failures (MTBF) for Voith control servo motors is over 103 years. Your equipment runs for a very long period of time without unplanned downtime; availability is increased. The control servo motor is also available in a redundant design (position feedback system and way valve control).
