Note 1) “L” option is the oil-free treatment.
Note 2) The dynamic viscosity of the fluid must not exceed 50 mm2/s.
The special construction of the armature adopted in the built-in full-wave rectifier type gives an improvement in OFF response by providing clearance on the
absorbed surface when it is switched ON.
Select the DC spec. or AC spec. built-in full-wave rectifier type when the dynamic viscosity is higher than water or when the OFF response is prioritized.
Note 3) Coil insulation type Class H: AC spec. only
Note 4) The nuts (non-wetted parts) are nickel-plated on the Brass (C37) material.
Note 5) There is no shading coil attached to the DC spec. or AC spec built-in full-wave rectifier type.

When the fluid is oil.
The dynamic viscosity of the fluid must not exceed 50
mm2/s.
The special construction of the armature adopted in the
built-in full-wave rectifier type gives an improvement in OFF
response by providing clearance on the absorbed surface
when it is switched ON.
Select the DC spec. or AC spec. built-in full-wave rectifier
type when the dynamic viscosity is higher than water or
when the OFF response is prioritized.

Working principles
Working principles
<Valve opened – when there is pressure>
When the coil o is energized, the armature assembly u is attacted into
the core of the tube assembly i and the pilot valve
is opened.
When the pilot valve is opened and the pressure inside the pilot chamber
decreases, resulting in the pressure difference from the inlet pressure. Then the diaphragm assembly e is lifted and the main valve
is
opened.
<Valve opened – when there is no pressure or under low minute pressure>
The armature assembly u and the diaphragm assembly e are connected with each other with the lift spring !0. When the armature assembly
is attracted, the diaphragm assembly is pulled up and the main valve
is opened.
<Valve closed>
When the coil o is de-energized, the armature assembly u returns by
the reacting force of the return spring r and the pilot valve
is closed.
When the pilot valve is closed, the pressure inside the pilot chamber
increases, resulting that the pressure difference from the inlet pressure
is lost and the main valve
is closed.
<Valve closed>
When the coil o is energized, the armature attacted by the core of the
tube assembly i closes the pilot valve
via the push rod assembly !1.
When the pilot valve is closed, the pressure inside the pilot chamber
increases, resulting in the pressure difference from the inlet pressure is
lost and the main valve
is closed.
<Valve opened – when there is pressure>
The coil o is de-energized, the armature returns by the reacting force of
the return spring r via the push rod assembly !1 and the pilot valve
is opened.
When the pilot valve is opened, the pressure inside the chamber
decreases, resulting in the pressure difference from the inlet pressure.
Then the diaphragm assembly e is lifted and the main valve
is
opened.
<Valve opened – when there is no pressure or under low minute pressure>
The push rod assembly !1 and the diaphragm assembly e are connected with each other with the lift spring !0. When the push rod assembly
returns, the diaphragm assembly is pulled up and the main valve
is
opened.
