Operation
Inlet flow passes through
the adjustable orifice and
the radial holes in the spool/
sleeve assembly then out
of the regulated port. The
pressure drop across the
orifice is sensed at each end
of the spool, producing a force
which, at the required flow
rate, overcomes the spring
force. The resultant movement
of the spool regulates the flow
by opening the radial valve
ports to the bypass port and
closing the regulated flow
ports.
The valve will pass flow in
the return direction but this
is restricted by the flow path
through the control orifice.
Features
Cartridge construction gives
versatility of application. A
valve may be fitted into a
line body, a custom designed
Hydraulic Integrated Circuit or
directly into a cylinder or other
actuator. Leakproof adjust
screw gives easy, accurate
adjustment to required flow
setting. Hardened and ground
working parts give accurate
flow control and long working
life.

Sectional View
Description
These valves are priority flow
regulators. The flow (and
actuator speed) will be largely
independent of the load and
the pressure conditions.
If used to regulate flow from
a fixed supply, for example a
standard gear or piston pump,
the valve will pass the required
flow and any surplus flow will
be diverted to the bypass port.
The bypass flow may be used
for a secondary circuit whether
the secondary pressure
requirement is higher or lower
than the regulated pressure.
The valve inlet pressure will
be approximately 7 bar (100
psi) more than the regulated
or bypass pressure, whichever
is higher.
