SK VXED2130 (8A/10A) Construction Normally closed (N.C.) Body material: Brass (C37) (32A or more: CAC407), Stainless steel (32A or more: not available) VXED2270/2380/2390 (32A to 50A) VXED2140/2150/2260 (10A to 25A) Working principle 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.
