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 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.
Valves are available in the following versions (see hydraulic symbol):
- 2 way pressure compensated
- 3 way pressure compensated
with priority function.
- 3 way pressure compensated
with priority and venting function.

• In order to obtain the 3 way pressure
compensated version the cavities 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.
