INPUT SIGNAL CURVES - FLOW RATE
ORDERING CODE
The open loop valves of series XDP... control the direction and the volume of the flow according
to the feeding current to the proportional solenoid. By using a valve body equipped with
increased passage channels it is possible to reach the highest capacity of its dimensions at a
parity of pressure drops, (40 l/min with ∆p of 10 bar).
Each ∆p variation on the valve leads to the variation of the capacity which has been set, anyway
the valve guarantees an high inner compensation grade and limits the adjustment capacity.
Performances shown in this catalogue are guaranteed only using 2 or 3 way modular
assembly hydrostats type AM.3.H. ... By using the valve with the base for capacity doubling
type BC.3.07 (see next page) a greater capacity cam be obtained.
