By connecting it to an actuator, a simple valve is turned into a control valve. Deviations in the control loop are regulated by the stroke movement of the valve plug. The required actuating force is supplied either electrically, pneumatically, or electro-pneumatically. Depending on version, an actuator can also be fitted with manual operation, position feedback, or safety switch-off.


Baelz offers a wide variety of tried and tested electric, pneumatic and electro-pneumatic actuators for control valves. Baelz actuators are durable, low-maintenance, and versatile in use. The product range is completed by special versions, e.g. with integral position controller. Decades of experience have gone into the designs, making for a high degree of operational safety and reliability.
