Overview
The MVT S range actuates push/pull and spring return valves on terminal units, zone valves, solar plants and small reheat and dehumidification coils. The S models have a maximum stroke of 9 mm and fit iSMA Controlli VSBT, VMBT, V.XT, 2TGA..B and VSXT..PBP valves, and the LIBRA series. The 3 point models run from 24 V AC (MVT403S) or 230 V AC (MVT203S). The proportional MVT503S runs from 24 V AC, accepts 0 to 10 V, 2 to 10 V, 0 to 5 V, 6 to 10 V or 4 to 20 mA, and gives a 2 to 10 V position feedback. It can calibrate its stroke automatically or use a fixed stroke for spring return valves. The actuator has a 1.5 m connection cable, a manual override reached with a 3 mm Allen key, and a force limit that stops the motor at 300 N.
