Enfield TR I/P Piloting RF Pinch Valve

Accurate fluid metering is achieved with an Enfield Technologies’ TR-010-g10-s proportional pressure regulator piloting a RF aiRFlex pinch valve. By increasing or decreasing the pilot pressure, the TR-010-g10-s I/P is able to adjust the opening of the pinch valve and the resultant amount of liquid flowing through.

In this video, a 0…25 psi range (scaled down from the full 0…145 psi range) is controlled with an inverted 4…20mA control signal. Both the scaling and inverting operations were preformed and saved within the TR valve software to allow for a direct drop-in without changing existing PLC code or infrastructure.
