Damages through mechanical loads
Mechanical loads applied to the valve body and
solenoid may lead to damages.
→ Avoid distorting the valve body in a misaligned
pipework. / Do not use inappropriate tools or
sealing material. / Do not use solenoid as a
lever during mounting.
The valve may be damaged by inadmissible
ope rating conditions at the operating site.
→ Protect valve from objects falling down.
→ Protect valve from direct weather influences.

6.1 Mounting position

The preferred mounting position is with the solenoid
upright to reduce risk of wear and contamination.

6.2 Mounting valve with thread connection
1. Observe the safety information in this chapter.
2. Take out the protective collars from valve inlet (P)
and valve outlet (A).
3. Firmly seal the threads of the pipeline with an
appropriate sealing material.
4. Attach the threads of the pipeline to the connec­
tion threads of the valve.
6.3 Mounting valve with flange connection
1. Observe the safety information in this chapter.
2. Take out the protective collars from valve inlet (P)
and valve outlet (A).
3. Screw the flanges of the valve body with the
flanges of the pipeline. Make sure that the flange
seal is correctly positioned.
4. Tighten screws with the required tightening
torque.
7. Connect solenoid electrically

DANGER
Hazardous electrical voltage
(>25V AC; >60V DC)
There are high risks from electrical
voltage during assembly works.
→ You must connect the earth wire to the termi­
nal marked with the grounding symbol
→ Only plug the device socket in de­energized
state.
→ Ensure correct polarity when connecting live
wires to terminals marked "+" and "–".

Faulty connection causes risks.
→ After connecting the solenoid carefully close
the terminal compartment to restore protec­
tion.
→ To secure IP 65 protection after connecting:
Carefully close the device socket. Check if the
flat seal between solenoid and device socket
is properly seated. Check if the cable gland is
properly sealed.
If the middle screw is tighten too much the
device socket's housing may distort.
→ Tighten middle screw of the device socket with
max. 40 Ncm ±10 Ncm. The housing must not
show signs of deformation.
→ Connect solenoid in accordance with the electri­
cal regulations.
→ Solenoids with pin layouts in accordance with
DIN EN 175301­803 and frequency range 40­
60 Hz must be connected through the supplied
rectifier/device connector.
8. Checking valve
8.1 Check switching function
→ It is advisable to carry out an operating test
without fluid before pressurising. The clicking
(impact) of the core must be audible during
switching.
8.2 Check for external leckage
1. Apply soap sud to the outer sealing edges and
check for the formation of bubbles.
2. In case of the formation of bubbles the valve
must not commissioned until the leakage has
been resolved.
8.3 Check for internal tightness and strength
→ Flood the valve and ensure to increase the
pressure slowly. NOTICE The valve must not be
operated during these tests. Tests for internal
tightness and strength with the valve open
are permitted at up to 1.5 times the maximum
working pressure.
