Function
The solenoid valve VZWP–L–M22C is a servo controlled
2/2-way valve with solenoid coil.
The solenoid valve VZWP–L–M22C is closed when de-ener
gised (Normally Closed - NC). When power is supplied, the
differential pressure is relieved from the secondary side of
the piston via the servo hole. The effective differential pres
sure lifts the piston away from the valve seat.
Fig. 2
The pilot function of the valve actuator can be used to control high pressures with
large nominal diameters by means of small solenoid coils.
The minimum differential pressure must always be present to ensure smooth func
tioning of the servo control (

Application
Solenoid valves of the series VZWP–L–M22C are intended to control the flow of
gaseous and fluid media in rigid piping systems.
The product may only be used in its original state without unauthorised modific
ations. Only the mounting and commissioning activities described in these oper
ating instructions are permissible. Do not open the valve body or dismantle the
armature guiding tube.
Do not use the product in closed circuits.
Do not use the VZWP solenoid valve as a safety component.
Use the product only in perfect technical condition.
Only use media in accordance with specification. Before using other media,
please contact our customer support.
Operation with chemically unstable gases, abrasive media and solids is imper
missible.
Use the solenoid valve only in the marked flow direction.

Installation
Note
Installation only by qualified personnel.
Avoid contamination. In this way you will prevent small holes from becoming
blocked (e.g. servo hole) and restriction or blockage of the function.
Avoid mechanical stresses especially on the solenoid coil and the armature
guiding tube.
Ensure sufficient thermal circulation at the installation location.
1. Before installation, check the system requirements:
– The tubing system is unpressurised and does not hold any medium.
– The pipelines are clean.
– The ends of the pipelines are mounted.
– The power supply is switched off.
2. Put the solenoid valve in its mounting position. Please note the flow direction.
The permissible flow direction is marked by an arrow on the valve body.
3. Screw the ends of the pipelines to the valve ports. Observe the permissible
tightening torques.
4. Establish the electrical connection. Use only the specified plug type (
è
Tech
nical data).
– Connect the electrical cable to the plug connector.
– Attach the seal to the electrical contacts.
– Plug in the plug connector and secure it in place with the mounting screw
(torque 0.3...0.5 Nm).
5. Connect the power supply.
