Operation
Flow into the inlet of the valve
passes through the adjustable
orifice and out of the regulated
port. The pressure drop across
the orifice is sensed on the
regulating sleeve and produces
a force which, at the required
flow rate, overcomes the
spring force. The resultant
movement of the sleeve
regulates the flow by closing
the radial valve ports.
The inbuilt check allows free
return of flow (2 to 1).
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
This is a two-port, restrictive
flow regulator with a built in
free flow check valve. Typical
uses include the control of
actuator speed by regulating
the flow into or out of the
actuator (meter-in or
meter-out).
The flow (and actuator speed)
will be largely independent
of the load and the pressure
conditions. If used to restrict
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 normally pass
over the system relief valve.
