About

Metal Work RegUp

Features
Read full description

Metal Work RegUp is the Metal Work® app for the remote configuration and control of the proportional pressure regulators series REGTRONIC, which have the job of precisely regulating the pressure in a system, the variables depending on the input command. Pressure control takes place in a “closed-loop” with an electronic precision pressure sensor that measures the downstream pressure, a control system that compares it with the desired pressure, and two mini solenoid valves that adjust the pressure to reach the target value. The regulators series REGTRONIC are available in analogue command version or with IO-Link interface, with or without display.
