Operation

Valve Opening
When the coil (12) is energized, the armature assembly (11) is attracted by the core (8), opening the pilot valve (A).
When (A) is opened, the pressure in the pressure action chamber (B) falls, opening the main valve (C).
Valve Closing
When the coil (12) is not energized, the pilot valve (A) closes and the pressure in the pressure action chamber (B) increases, closing the main valve (C).

14	Solenoid Coil		Cu + Fe + resin

Operation

Valve Opening
When the coil (14) is energized, the opened pilot valve (A) closes and the pressure in the pressure action chamber (B) increases, closing the main valve (C).
Valve Closing
When the coil (14) is not energized, the closed pilot valve (A) opens and the pressure in the pressure action chamber (B) drops, opening the main valve (C).
