NOTICE
Wear, tear and malfunctions!
The cleanliness of the hydraulic fluid has a considerable impact on the cleanliness
and life cycle of the valve. Any contamination of the hydraulic fluid will result in
wear and malfunctions. Particularly foreign particles may damage the valve.
▶ Always ensure absolute cleanliness.
▶ Install the valve so that it is free from dirt.
▶ Make sure that all connections, hydraulic lines and attachment parts are clean.
▶ Ensure that no cleaning agents are able to penetrate the hydraulic system.
▶ Do not use hemp as a sealant under any circumstances.
To ensure proper functioning, care must be taken that the pressure chamber of
the solenoid is always filled with hydraulic fluid and the tank line must not be
allowed to run empty. With corresponding installation conditions, a preload valve
providing a preload pressure of approx. 2 bar must be installed in the tank line.
1. Before any assembly and disassembly work starts, the surroundings must be
cleaned so that no dirt can get into the oil circuit. Only fibre-free cloth or special
paper may be used for cleaning.
2. Remove existing preservative agent.
3. Check the valve contact surface for the required surface quality
(see"Datasheet29184-XE"). Remove the protective plate from the valve
andkeepit safe for returns in case any repairs become necessary later.
4. Dry the valve connection surface using suitable cleaning materials.
5. Check the seal rings at the valve connection surface for completeness.
Othersealants are not admissible.
6. Place the valve on the contact surface.
For reasons of stability, exclusively use the valve mounting screws specified in
chapter 7.6 "Required accessories"!
Always fasten the valve with all 4 valve mounting screws as otherwise, leak-
tightness is not guaranteed.
7. When using the subplates mentioned in 7.6 "Required accessories" or in case
of assembly on comparable cast iron installation surfaces, tighten all four valve
mounting screws using a torque power screwdriver
(tolerance ≤ 10%) and a tightening torque of 7Nm [5.2 ft-lbs] ± 10%. This
tightening torque refers to the maximum admissible operating pressure.
