(A) OPERATING PRINCIPLE
In de-energized condition of solenoid, applied pressure at Inlet port # 2, a part of media pressure passed from bleed
hole of diaphragm to surrounding hole of Duse to tube hole to out let port # 1. thus, pressure released from top of the
diaphragm assembly and it is moves up. In this state, Inlet port # 2 and Outlet port # 1 is connected. Media come from
outlet.
In energized condition of solenoid, thus plunger assembly moves up and blocked the pilot passage, now applied
pressure at Inlet port # 2, media pressure act on the diaphragm assembly from bleed to keep downwards. In this state,
Inlet port # 2 and Outlet port # 1 is disconnected. Media cannot come out.
