VALVES
CETOP 3
The sequence valve are used to as-
sure that a secondary circuit is pres-
surized when the setting pressure is
reached.
These valves grant a minimum varia-
tion of the setting pressure with a
changing flow up to 40 l/min (see
diagram).
Three spring types allow adjustment
within the range 7 ÷ 250 bar. Manual
adjustment is available by a grub screw
or plastic knob.
The cartridge used is the "CVS" type.

To changes valves AM.3.VS... from internal to exter-
nal drainage it is necessary:
- screw out the plug on the Y port
- screw out the plug T.C.E.I. M8x1 from the body
- screw in a screw S.T.E.I. M6
- rescrew the T.C.E.I. M8x1 plug on the body
NOTE: the external draining can be used as a piloting
line (please, contact our Technical Service for other
informations)
