Small and energy-efficient:
simply use the energy of the medium.
The force pilot operated VZWF can thus
control high pressures with high nominal
diameters using relatively small solenoids –
even in closed media circuits with no
differential pressure. It activates even at
0 bar and automatically closes when the
pressure drops, thanks to the N/C function.
• For gaseous and liquid media with
a max. viscosity of 22 mm²/s
• For water, air and neutral media
• For filling systems (secondary circuit),
water treatment, heating circuits, etc.
Force pilot operated
solenoid valve VZWF
Doesn't let you down, even with high
pressures and low flow rates.
VZWD even works in closed media circuits
with no differential pressure up to 90 bar,
making it ideal for high-pressure cleaning
and dosing, gas supply to DIN EN 161 or
safety shut-off functions. As it does not have
any control boreholes, it even works when
slightly contaminated.
• Valve switching from 0 to 90 bar;
vacuum technology to 100 mbar
• Works with water, air and neutral media up
to a maximum viscosity of 22 mm²/s
• Integrated N/C function
Directly actuated
solenoid valve VZWD
Open the door to new applications with
a greater operating pressure range –
of up to 40 bar.
VZWP is the latest addition to the solenoid
valve series VZWM. The VZWP uses a sealing
piston instead of a diaphragm, allowing it to
control high pressures with large nominal
diameters. It is ideal for use with gaseous
and fluid substances up to a viscosity of max.
22 mm²/s in production and process
automation.
• Brass valves with selectable NBR and FKM
seals
• N/C function closes solenoid valve on loss
of power
• For open media circuits with a differential
pressure of at least 0.5 bar
