DESCRIPTION
Special cavity, pressure compensating valve, bypass type, for 3 way ow control, normally closed.
OPERATION
The QC-CP3 with an orice between ports (3) and (1) maintains a constant ow rate from (3) regardless of load
pressure changes in the system upstream of (3), or in the bypass leg at (2) as long as pressure at (2) is less than
(1). The valve’s spool maintains a constant differential pressure across an external orice, thereby regulating the
hydraulic ow rate from (3) to (2), (see options table for pressure ranges). When used with an orice as described
above, as a priority type regulator, delivering pump ow rst to (3), then bypassing excess to (2). All ports may
be fully pressurized.
FEATURES
Hardened parts for long life.
Spring range from 8 to 24 bar.
