VXZ EU
Pilot Operated/Zero Pressure Differential Operation
2 Port Solenoid Valve
Series
VXZ
Change of valve style from
N.C. to N.O. is simple.
Low power consumption,
long life, and high reliability
type molded coil
Excellent maintainability
VXZ22 7.5/6W (50/60Hz AC)
VXZ23 11/9.5W (50/60Hz AC)
Separation of movable iron core
and diaphragm valve permits easy
disassembly/reassembly.
Compact, light, and large
valve capacity
Diaphragm
Strong against dust and
water scale in fluid.
Wide variations permit use
of almost all types of fluid.
Zero pressure
differential operation
Usable under conditions of
vacuum –101.2kPa to 1MPa
(AC, water/air).

When power is not supplied
Fluid from the IN side goes through the
supply orifice and fills the pressure action
chamber.
The main valve is kept closed by the force
pushing down the valve and the reaction
force of the return spring.
Right after power is supplied (Pilot valve opens)
When power is supplied to the coil, the
armature begins to be attracted, and the
pilot orifice opens.
The fluid filled in the pressure action chamber flows through the pilot orifice to the
OUT side.
When power is being supplied (Main valve opens.)
Since the fluid is discharged from the pilot orifice,
the pressure in the pressure action chamber
decreases.
The force pushing down the valve weakens, and
the pressure pushing up the valve over-comes
the said force. Thus the main valve opens.
When the IN side has no pressure, or when the
pressure is very low,the reaction force of the lift
spring opens the main valve.
