Description
A screw-in, catridge-style ,spool- type pressure-compensating element,
port 3 can be used in blocking or load-holding circuits, intened for use
with a remote xed or variable orice to yield a two-port-type, pressure-
compensated, ow regulating hydraulic valve.
Operation
The valve maintains a constant ow rate from ② regardless of load
pressure changes in the circuit downstream of ② .
The cartridge maintains a constant dierential pressure from point ③
to port ① , thereby regulating the hydraulic ow rate between the two
points in the circuit.
When the adjustable ow orice is completely closed, the oil port ③ cuts
o the ow of oil and the P-port load can be maintained.
