Activity description
Installation of a direct-acting solenoid valve
The installation may occur only in state without pressure!
We recommend the installation with the valve in upright position!
The power supply must be done on site by a qualified electrician!!
You don't need any special tools to connect the solenoid valve with your piping system.
Function
Direct acting solenoid valves are always in the state "normally closed". In rest position the
plunger locks the seat only by spring force. When the solenoid is energized the plunger with its
sealing is directly lifted from the seat. With a larger set diameter, the permitted operating pressure
decreases and the magnet strength must be increased.
IMPORTANT! Our common solenoid valves are always in the state "normally closed"!
Setting-up operation
Depending on the area of use, surface temperatures higher or lower than the ambient
temperatures may occur on the valve housing. In system engineering, pipes with large
temperature differences relative to the ambient temperature are usually insulated accordingly to
save energy. This insulation should also include the housing of the industrial valve. The solenoid
must not be insulated both for thermal reasons (heat build-up) and also to permit easy
maintenance. Insulating the housing excludes the possible risk of burns. The decision regarding
insulation is taken by the system engineer and is thus his responsibility. Finally, there is a small
residual risk caused by high temperature on the solenoid, which depends on the frequency of
operation.
