2.2 Adjustment of the discharge valve
The discharge valve is delivered from the plant with the main
adjustment. The necessary rotation of the spindle for this
adjustment is given on the picture situated on the pilot (see
drawing on the right).
By turning the spindle left to the bleed adjustment " - ", it is
possible to adapt the device to special operation instructions
-additionally to change the auxiliary pressure-
f.i. by regulation variations of "pressure picks" after a quick
closing of the stop organ preswitched.
3. Special Maintenance Instructions
3.1 Auxiliary pressure stage (see page 8)
Diaphragm (68)
By dismantling, put the cover (69) off, put the diaphragm (68) on the side of the inlet pressure connection and
hang the diaphragm on the side outside the joint (80).
Sealing cone (81)
To dismantle the sealing cone, the screws (98) must be unscrewed and the complete joint (80)
must be put off. A mark of the sleeve corner (83) on the sealing surface of the sealing cone (81) is normal.
By installing the sealing cone, the position of the lever joint must be controlled after the installation of the joint and
newly adjusted if necessary.
The correct adjustment is given if the lever is manually put out (piston in closing position) and the superior corner of
the lever is parallel to the diaphragm support.
A possible and necessary correction is obtained by underlaying the different thicker sealing rings (51, 85) under the
intermediary piece.
3.2 Control stage - Tool M and N (see p. 6 and 8)
Control rod (16, 76)
The control rod must lightly slide in its conduction. By installing the new parts in the outlet pressure stage the
adjustment measure of the rod must be controlled according to the measurement tool and be corrected if necessary.
The adjustment measure must be put off according to the following drawing.
