Fast-closing valves and
medium controlled Fast-closing valves
Servo motors / control cylinders
Servo motors regulate the amount of steam in the steam turbine by controlling the control valves.
- Actuators with force switch
- Actuators with electro-hydraulic transducer (EHW), e.g. Voith valves, Schneider valves, Moog valves, Balluff displacement transducers
- Actuators from various manufacturers (Siemens, Voith, Duplomatic, Bosch Rexroth, Parker)

Oil control valves
Oil control valves control the oil pressure in the oil system. They are virtually maintenance-free as they are completely integrated into the oil system. Only 4 types cover a wide flow range.
We offer:
- Pre-pressure control valves
- Overflow valves (upstream pressure control valves with test screw)
- Pressure reducing valves
Safety blocks
We manufacture safety blocks 2 out of 3 and also the old AEG-Kanis variant, often called sandwich block.
