Aron AD5IP001 Valve

AD.5.I... AUTOMATIC RECIPROCATING
VALVES CETOP 5 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 preferential 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 capable of changing over the valve
and inverting the cylinder direction of the movement.

AD.5.I.P.2T.1 FOR REGENERATIVE SYSTEM
P→A A→T
Tests carried out with mineral oil a temperature of 40°C with a viscosity of 46 mm2/s.
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
