ORDERING CODE
The fluid used is a mineral based oil with a
viscosity of 46 mm
2
/s at 40°C. The tests have
been carried out at with a fluid of a 40°C.
The open loop proportional flow regulator 3 way compensated with priority
function is designed to regulate flow in proportion to an applied electrical current
(REM or CEP.S power amplifier).

Operating specifications and overall size make
this valve suitable to interlock to module units
and stackable valves in order to combine a
proportional control with directional control typi-
cal of stackable systems.
The body valve is white zinc plated.
Flow regulation is independent both from load – P
OUT
port – and pump flow variations. Load
compensation is achieved by a spool compensator, which holds the pressure drop constant
across the proportional spool.
