7 Water Hammer Relief, Pilot Operated Port Solenoid Valve Series VXR//3 For Water and Oil Construction/Principal Parts Material Normally Closed (N.C.) Normally Open (N.O.) Operation < Valve opened > When the coil o is energized the armature assembly u is attracted into the core of the core assembly y and the pilot valve A opens. Then the pressure in the pressure action chamber B falls to open the main valve C. < Valve closed > When the coil o 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. Water hammer relieving Check valve mechanism is provided in the E side of the supply orifice and E and supply into the pressure action chamber B can be controlled with two stages by moving the diaphragm assembly r. After release of the energy, when the open amount of the main valve C becomes small, E is blocked. A low valve closing speed relieves the water hammer.
