ILOTED VALVES CETOP 5/NG10
WITH CETOP 2/NG4 PILOT VALVE
These ADPH 5 valves are used primarily for controlling
the starting, stopping and direction of fluid flow. These
kind of distributors are composed by a main stage crossed
by the big flow from the pump (ADPH.5) and by a cetop 2
pilot directional solenoid valve (AD.2.E) available with
different mounting type .
When a short response time is requested, a special
version of solenoids with high dynamics is available with
the code AD.2.E.**.*.*FF.2 (Please, contact our Techni-
cal Aron Service).

The diagram at the side shows the pressure drop curves for spools
during normal usage. The used fluid is a mineral oil with a viscosity of
46 mm
2
/s at 40°C; the tests have been carried out at a fluid temperature
of 40°C. For flow rates higher than those in the diagram, the losses will
be those expressed by the following formula:
∆p1 = ∆p x (Q1/Q)
2
where ∆p will be the value for the losses for a specific flow rate Q which
can be obtained from the diagram, ∆p1 will be the value of the losses
for the flow rate Q1 that is used.

Mounting surface
When the main spool connect P to T in the centre position,
the minimum pressure of 10 bar is needed to move the main
spool (see the “Specifications”); for this reason a check
valve on the P line (see the drawing above) is necessary.
