Pilot operated, pressure reducing valve with drilled
piston orifice
Capacity:
80 gpm (320
L/min.)
Functional Group:
Products : Cartridges : Reducing : 3 Port : Pilot Operated Reducer, Drilled
Piston Orifice
Model:
PBJF
Product Description
Pilot-operated, pressure reducing valves reduce a high primary pressure at the
inlet (port 2) to a constant reduced pressure at port 1, allowing circuits with
multiple pressure requirements to be operated using a single pump.

Technical Features
These valves have the main stage orifice drilled
into the piston rather than a staked-in orifice. This
allows the valve to survive physically demanding
applications.
Pilot operated valves exhibit exceptionally flat
pressure/flow characteristics, are very stable and
have low hysteresis.
All three-port pressure reducing and
reducing/relieving cartridges are physically
interchangeable (i.e. same flow path, same cavity
Pressure at port 3 is directly additive to the valve
setting at a 1:1 ratio and should not exceed 5000
psi (350 bar).
for a given frame size). When considering
mounting configurations, it is sometimes
recommended that a full capacity return line (port
3) be used with reducing/relieving cartridges.
Full
reverse flow from reduced pressure (port 1) to
inlet
(port 2) may cause the main spool to close. If
reverse
free flow is required in the circuit, consider
adding a separate check valve to the circuit.
Pilot operated reducing, reducing/relieving valves
by nature are not fast acting valves. For superior
dynamic response, consider direct acting valves.
If pilot flow consumption is critical, consider using
direct acting reducing/relieving valves.
Incorporates the Sun floating style construction to
minimize the possibility of internal parts binding
due to excessive installation torque and/or
cavity/cartridge machining variations.
Recommended maximum inlet pressure is
determined by the adjustment
range. Ranges D, E,
N, and Q are tested with a 2000 psi (140 bar)
maximum differential between inlet and reduced
pressure. Ranges A, B, and H are tested with a
3000 psi (210 bar) maximum differential between
inlet and reduced pressure. Ranges C and W are
tested with 5000 psi (350 bar) of inlet pressure.
