Operation
This valve, when used with
either a fixed or variable orifice
between port 1 and port 3,
maintains a constant flow.
This is based on what ever
pressure differential is chosen.
Flow out of port2, regardless
of pressure, changes
downstream on port2.
Features
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.
Performance Characteristics
Cartridge only

Description
This is a restrictive style
compensator suitable for use
with a separate needle valve
or orifice to provide a pressure
compensated flow while
the excess oil passes over a
relief valve or closes down
the compensator on a pump.
This, when used in a manifold,
is ideal for motor or cylinder
speed control either meter in
or meter out.
Controlled flow - L/min (21,8 cSt oil @ 49°C)
Controlled flow - USgpm (105 SUS oil @ 120°F)
