Electric pressure reducing valve VF43

• Contact us

Electric pressure reducing valve is a typical application of electric regulating valve in the field of pressure control. The Siemens/chenxuan electric pressure reducing valve achieves the purpose of controlling the pressure behind the pressure reducing valve by adjusting the dynamic pressure head of the primary side fluid. The pressure sensor is installed on downstream of the steam pipe to monitor synchronously the steam pressure after decompression . The multi-function pressure reducing controller uses the PI (proportional integral) mode to adjust the opening of the valve to reach the steam pressure closer to the set value. Regardless of how the upstream and downstream loads change, the downstream steam pressure remains stable, ensuring safe operation of the rear equipment.

Electric pressure reducing valve details:
DJY series electric pressure reducing valve is a typical application of electric control valve in the field of pressure control. The purpose of controlling the pressure after the pressure reducing valve is achieved by adjusting the dynamic pressure head of the primary side fluid. Electric pressure reducing valve is a typical application of electric regulating valve in the field of pressure control. The pressure reducing valve achieves the purpose of controlling the pressure of the pressure reducing valve by adjusting the opening degree of the valve.

The pressure sensor is installed on downstream of the steam pipe to monitor synchronous the pressure change after decompression,converting the pressure into 0-10V electric signal and transmit it to the PI controller. The controller performs comparison operation according to the set pressure value, and outputs The control signal to adjust the valve opening,leads the post-valve pressure to approach the set value. The downstream steam pressure remains stable regardless of fluctuations in upstream pressure or changes in downstream load.
