Note:
Associated tools for production of ports can be ordered from the valve manufacturer (SMT catalogue 0019).Drawings of the ports are also available
in the same catalogue.
Unscrew the coil nut (4) by turning it counterclockwise. Remove the coil seal ring (3) and coil (2) from the control system.
The valve (1) is mounted in the chamber without the spool to prevent the valve from tightening in the chamber. Before inserting the valve into the
chamber in the block, ensure that undamaged seals are fitted to the valve housing. Also verify that the valve and chamber surfaces are not damaged
or contaminated. Before installing the valve, we recommend lightly lubricating the housing seals with grease or working fluid. Using slight pressure,
carefully insert the valve into the chamber and turn it clockwise to screw it in by hand. Then tighten the valve to 35 + 5 Nm, using a torque wrench
(a = 27). Place the spool (2), spool seal (3) and fixing nut (4) back on the valve control system.
Orient the spool by turning it on the control system so that the cable outlet points in the required direction and secure the position of the spool by
tightening the nut clockwise with a torque wrench (a = 36) to 5 + 1 Nm.
