Dimensions Of Screw-In Poppet Valve - Argo-Hytos SD3EX-B2 Gebrauchsanweisung

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.

CAUTION
The solenoid windings heat up during operation. Effective external cooling must be provided to ensure that the maximum winding temperature is not
exceeded, by not exceeding the maximum fluid and ambient temperature and by maintaining minimum volume of the connection block. A valve
body volume of (225cm ) is sufficient for one manifold. If several valves that can be switched simultaneously are connected on the connection plate,
3
a distance of at least 55mm must be maintained between the bodies of adjacent valves (see fig).

Correct installation of the valve
A missing or damaged ring after the thread will cause a leak of working fluid. Missing or damaged rings on
the valve body will cause internal volume loss and unreliable valve operation.
