5 Installation and connection
5.1 Preparing the installation
5.1.1 Checking conditions of use
§ Make sure that the valve design is suitable for the intended use:
- Materials used
- Medium
§ Ensures the necessary conditions of use
- The resistance of the materials used for the body and seals against the medium
- Media temperature
- Operating pressure
§ Agree any other use with the manufacturer
5.2 Planning pipelines
5.2.1 Designing pipelines
WARNING
Danger of poisoning and environmental damage from the medium
Leakage due to leaks caused by impermissible pipeline forces.
Make sure that no tensile or compressive forces and no bending
moments act on the armature.
§ Plan pipelines with safety in mind
- Ensure there are no tensile or compressive forces
- Ensure there are no bending moments
- Compensate for changes in length caused by temperature fluctuations
- Observe the direction of flow
- Pay close attention to the fitting position and direction of the valve
- Apply suitable measures to prevent pressure surges
§ Dimensions (3.3 Design and dimensions)
§ Fit dirt traps to ensure proper functioning

5 Installation and connection
15/23 OPERATING INSTRUCTIONS FOR METAL SOLENOID-VALVES Index: 0
5.3 Fitting the valve to a pipeline
WARNING
De-pressurised fitting.
Only fit the valve to de-pressurised pipelines.
WARNING
Danger of poisoning and environmental damage from the medium
Leakage due to incorrect installation.
Installation work on the pipelines must only be carried out by skilled
workers who are trained for the respective pipeline system.
NOTE
Improper installation of the valve can cause damage to property
Fit the armature horizontally or vertically.
Ideally, fit the armature with the solenoid coil pointing upwards.
NOTE
Contamination in the valve can cause damage to property
Make sure that no contamination can enter the armature.
Flush the pipeline with a neutral medium.
The procedure used to fit the armature is determined by the type of connection to the pipeline.
5.3.1 Threaded connection
§ Screw the threaded connection onto the pipe in accordance with the applicable standard.
§ Use suitable sealing materials depending on the design and intended purpose.
5.3.2 Connection with flange
§ Check that the sealing face is free of damage and clean.
§ Carefully align the flange in front of the threaded joint.
§ Centre the seals (use suitable sealing material).
§ Connect the valve flange and pipe flange with the seal and suitable bolts.
§ Tighten the bolts cross-wise. Use all of the flange holes!
§ Only use permissible joining elements.

5 Installation and connection
16/23 OPERATING INSTRUCTIONS FOR METAL SOLENOID-VALVES Index: 0
5.4 Electrical connection
DANGER
Danger to life due to electric shock
Only allow an electrician to work on the electrical system.
Switch off the power supply to the system and secure it to prevent it
from being accidentally switched on again.
Connect protective conductors.
§ Before making the electrical connection, check that the current type and voltage are correct
(see data sheet).
§ Make sure that the device plug connection is protected against constant moisture. If
necessary, fit a protective cover.
§ Connect the cable to the device.
§ Connect protective conductors.
§ Insert device plug into connector on the valve.
5.4.1 Plug assignment
HINWEIS
Plug
Plug according to DIN EN 175301-803.
1 Supply voltage
2 Supply voltage
3 Protective earth conductor
5.5 Carry out a pressure check
NOTE
Medium pressure check
Carry out the pressure check using a neutral medium (e.g. water).
§ Pressurise the valve. When doing so, ensure that:
- Test pressure < permissible system pressure
- Test pressure < 1.5 PN
§ Check that the valve is leak-tight.

6 Operation
17/23 OPERATING INSTRUCTIONS FOR METAL SOLENOID-VALVES Index: 0
6 Operation
6.1 Commissioning
The valve must be correctly assembled and connected.
WARNING
Danger of poisoning and environmental damage from the medium
Leakage due to leaks caused by impermissible pipeline forces.
Make sure that no tensile or compressive forces and no bending
moments act on the armature.
NOTE
Overheating will destroy the alternating voltage solenoids
When commissioning the valve equipped with an alternating voltage
solenoid, make sure that the solenoid coil is mounted on the plunger
guide.
§ On the Types EV04-05 and MV04-05, make sure that the required differential pressure is
applied between the valve inlet and valve outlet.
§ After it is first exposed to pressure and operating temperatures, check that the valve is leak-
tight.

7 Maintenance and repairs
18/23 OPERATING INSTRUCTIONS FOR METAL SOLENOID-VALVES Index: 0
7 Maintenance and repairs
