WITT leads the way: Electrical proportional valves now control the pressure regulators of gas supply systems.
For the first time, the German manufacturer is supplying a retrofit module for dome-loaded pressure regulators (dome pressure reducers), thus allowing the operating pressure to be controlled remotely.
The advantage: Even complex production processes can be monitored optimally, as the required gas pressure of every process step is automatically communicated and set by the regulator.
Using programmable logic controllers (PLC), the electrical proportional valve is controlled via either the electrical current (Ampere) or the voltage (Volt). Because pressure transmitters record and monitor the back pressure, setpoint deviations can be detected and automatically compensated for by the system.
