E-MI-AS drivers can drive one coli of single or double solenoid proportional valve. These digital drivers are designed for mounting on the solenoid’s DIN connector of proportional valves without transducer.
Format type: DIN 43650 plug-in, power supply: 24 VDC (standard) or 12 VDC
Digital drivers control the current to the solenoid of proportional valves without transducer, according to the electronic reference input signal. The solenoid proportionally transforms the current into a force, acting on the valve spool or poppet, against a reacting spring, thus providing the hydraulic regulation. The hydraulic regulation means regulation of flow (velocity) or pressure (moment or force of a mechanical system).
