HYDRAULIC SYMBOLS
ORDERING CODE
The open loop proportional flow regulator is 2 and 3 way compensated with priority function.
It is designed to regulate flow in proportion to an applied electrical current (REM or SE3AN
power amplifier). Flow regulation is load independent - B port. Load compensation is achieved
by a spool compensator which holds the pressure drop constant across the proportional spool.

The tests have been carried out at with a fluid of a 40°C.
SIMPLIFIED TYPE
• In order to obtain the 3 way pressure
compensated version the cavity T have be
closed on the subplate.
• In order to obtain the 2 way pressure
compensated version the cavities P and T
have be closed on the subplate.
Valves are available in the following ver-
sions (see hydraulic symbol):
- 2 way pressure compensated - 3 way
pressure compensated with priority func-
tion.
- 3 way pressure compensated with priority
and venting function.
