2/3 Direct Acting Solenoid Valve Normally Closed (3S035
Series)
As shown
below, when the valve is de-energized (left diagram), the plunger under the
force of spring seals the main orifice, and port CYL connects with port EX.
When the valve is energized (right diagram), the coil magnetic force pulls
back the plunger and closes port EX, and connects port IN to CYL.
