Engineering notes
The characteristics of the main valve and the manufacturer's recommendations
must be observed.
Mounting notes
Mounting instructions are enclosed with the valve:
∂ Nr. 35552 (pilot valve)
The pilot valve can be mounted in any orientation, but upright mounting is preferable.
To protect the valve from dirt, a mesh filter should be fitted on the supply side (mesh
gauge 0.1...0.2 mm).
The pilot valve can be fitted directly to various commercially available main valves, with
the M24 x 1.5 screwed spigot.
Note, however, that it must not be screwed into the valve body until welding or solder-
ing work is complete.
To prevent damage to the O-ring and to protect the pilot valve from dirt and metal fill-
ings, the protective cap on the spigot should not be removed until immediately before
the valve is fitted.
Always switch off the power supply before connecting or disconnecting the ZM.. termi-
nal housing.

The pilot valve cannot be repaired. It has to be replaced as a complete unit.
