IMF proportional reducers are 3 ways pressure regulators:
1 – Inlet pressure
2 – Regulated outlet pressure
3 – Vent of the out let pressure
They are activated by an electromagnet powered with 24 VDC, which receives an input signal in current 4 - 20 mA or in tension 0 - 10 V.
The outlet pressure regulated is proportional in the input signal applied to the device.The basic calibration is as follows:
Max input signal = Max outlet pressure (example 20 mA = 100 bar)
Min input signal = Min outlet pressure (example 4 mA = 0 bar).
This calibration can be modified upon request.IMF proportional reducers are exclusivly designed for pressure pilot and pressure control.They are not designed for pressure regulation with a constant flow rate.A pressure sensor records the immediate outlet pressure and the PID electronic card corrects this pressure value: this is called closed regulation circuit.
This technology implies that the proportional regulator does not work with an external regulation circuit.(another input signal from an external pressure transmitter).
IMF proportional reducers are designed with balanced valves (patented principle). this technology is already used in other IMF reducers and it allows proportional reducers to be used with non constant inlet pressure from bottle or tank.
When there is no electrical power and/or no input signal, the inlet pressure is blocked and the outlet pressure goes to the vent
