AD.5.I.P.2T.1 FOR REGENERATIVE SYSTEM
PRESSURE DROPS
Version AD.5.I.P.2T.1 integrated in a regenerative circuit for
compactors with roll on-off mobile system, solution useful for all
applications where to connect microswitch of proximity is not
possible. For any information about our regenerative manifold
Aron please contact our technical department. For special subplate
BS.5.RIA see Chapter X "Systems", next pages.

specifications
The operating principle of this type of
inverter valve, with interface UNI ISO
4401 - 05 - 04 - 0 - 94 standard (ex
CETOP R 35 H 4.2-4-05), is based on
the pressure unbalanced created in
its interior as a consequence of the
fluid flow rate. On starting the system
this valve assumes always a prefer-
ential position P → B e A → T.
When a pressure is applied to the
cylinder which exceeds the system
maximum flow rate valve calibration
value (e.g. end stroke actuator), a
hydraulic unbalanced is generated ca-
pable of changing over the valve and
inverting the cylinder direction of the
movement.
