The Fahlke regulating controls used by all gas providers are available in pneumatic and electrohydraulic version. The controlled valve actuators as well as the associated valves can be moved between 0° and 90° exactly to any desired position in the tenth range (0.1% or <0.1°). In this way, the pressure or flow of your pipeline is safely and accurately regulated.
In combination with high pilots or line break detection systems integrated in the control you can implement quick strokes as well as safety-related protections.
The advantages of the Fahlke regulating units are obvious: Speed, accuracy and operational safety.
Available for double-acting or single-acting spring-return actuators
Control cabinet made of corrosion-free stainless steel
The regulating actuator remains in position or moves to the failsafe position in the event of failure of the control voltage
