Abstract
A solenoid valve (100) comprising a solenoid assembly (104) and a dual valve assembly (102) for fluid flow control and pressure relief. The dual valve assembly (102) comprising a valve body (300), upper stopper ring (113) and a lower stopper ring (307). A flow arrangement (200) comprising, a primary moving assembly (240) and a secondary moving assembly (213) is disposed inside the valve body (300). The primary moving assembly (240) having a primary mover (230) and an O-ring holder (208). The secondary moving assembly (213) comprising a sliding member (215), a supporting ring (214), a pressure-relief spring (211) and a pressure-adjusting mechanism (205). The flow arrangement (200) moves up when a solenoid coil (103) is energized resulting in normal fluid flow, the secondary moving assembly (213) moves down under excessive fluid pressure with the solenoid coil (103) de-energized. A reverse fluid flow is facilitated under excessive fluid pressure.
