Operation
This valve, when used with
either a fixed or variable
orifice on port 4, maintains
a constant flow out of port
3, regardless of pressure
changes downstream of port
3. This is based on whatever
pressure differential is chosen.
All flow in excess of
the priority requirement is
bypassed from port 1 to
port 2. If the priority port is
deadheaded, the valve will
try to direct flow out of the
priority port and shut off the
bypass flow, blocking of all
flow.
Features
Hardened and ground and
honed working components.
Cartridge construction for
maximum mounting flexibility.

Description
This is a priority style
compensator suitable for use
with a separate needle valve
or orifice to provide a priority
pressure compensated flow.
This when used in a manifold
is ideal for motor or cylinder
control where priority is
required.
