SOLENOID VALVES
1.2.
Installation
Clean fluids and gases
The solenoid valve can be used in combination with clean liquids or
gases. Check if there is any dirt in the piping or valve before installing.
It is recommended to install a filter (500 µm) before the solenoid valve.
Mounting the valve
Be aware of the direction of flow of the medium when installing the
valve. Solenoid valves with an arrow on the housing must be connected
in the indicated direction. The pipes on both sides of the valve must be
securely fastened. Use a wrench for both valve and pipe while
tightening to prevent unnecessary stresses in the system. The solenoid
valve must be fixed via the provided connection points. Only exert force
at the designated areas on the body such as the hexagon; never to the
coil or armature. Avoid vibration in the pipes. Use a suitable sealant for
threaded connections of the solenoid valve. Avoid the entry of thread
sealing material in the valve, this can lead to malfunctioning of the
valve.
Position
It is recommended to install the solenoid in vertical position with the
coil facing upwards. This reduces the probability of the collection of
debris in the solenoid valve. When the solenoid valve is mounted at an
angle, it is recommended to deviate maximally 90° from the vertical
position.
Maximum angle 90°.

Check the flow direction with the help of the indications on the valve
body.
Only exert force at the designated faces, never at the coil or armature.
Installation of the coil
►
Make sure the coil is labeled with the valve characteristics. The
device can be damaged by the use of unsuitable tools.
►
The temperature of the coil increases during use, this is normal.
Overheating will cause smoke and a burning smell. In this case,
the power supply must be shut down immediately.
►
The coils can be rotated if the coil nut is loosened. After the
determination of the correct position, the nut should be fastened
with a torque of 5Nm.
Installation of the cable plug
►
Always connect the ground (3), which is provided with a
residual current device at voltages above 50V. Never use
liquid or gas piping for grounding electrical equipment. The
power supply is connected to terminals (1) and (2). The
polarity does not matter.
►
Verify the voltage and frequency before connecting the coil.
►
When mounting the connector, make sure that no moisture
can ingress between the coil and connector. The connector
screws should be fastened with a torque of 0.5Nm.
Connecting the power supply
►
Never connect power to the coil when it is not attached to
the solenoid valve! The coil may burn out.
►
Only connect power if you are sure that there is no pressure
in the system and no hazardous situations can occur.
