Construction VXD2270, 2380, 2390 (32A to 50A) VXD2140, 2150, 2260 (10A to 25A) Operation When the coil !0 is energized, the armature assembly i is attracted into the core of the tube assembly u and the pilot valve A opens. Then the pressure in the pressure action chamber B falls to open the main valve C. When the coil !0 is not energized, the pilot valve A is closed and the pressure in the pressure action chamber B rises and the main valve C closes.
