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 solenoid valve
vents the spring chamber to a
drain line and in its NORMAL
(de-energized) mode all inlet
flow is diverted to the bypass
port. The pre-set regulated
flow is selected by energizing
the solenoid. The adjustable
relief valve vents the spring
chamber at the pre-set
pressure and diverts the flow
to the bypass port. It may
be necessary to fit a 10 bar
check valve in the bypass or
regulated line to ensure the
valve switches fully.
Features
Line body construction with
three ports allows direct
connection into hydraulic
systems. Leakproof adjust
screw gives easy, accurate
adjustment to required flow
setting. Remote functional
selection with solenoid
operation. Adjustable relief
valve gives system protection.
Hardened and ground working
parts give accurate flow
control and long working life.
