Goyen BWJ series 2/2 normally closed solenoid valve

Valves are actuated by a solenoid pilot, using an internal bleed. A diaphragm provices the seal for the main orifice. The pressure within the valve is utilised to open and close the diaphragm. The BWJ series use a coupled diaphragm design which is mechanically held open via a direct linkage to the solenoid plunger. This enables the valve to operate with zero pressure differential across the main valve orifice.
