Operation
This valve allows flow
between ports 3 and 4 while
blocking port 2 until sufficient
pressure has been applied to
port 1 and the spring bias is
overcome.
At that time flow is directed
between ports 3 and 2 while
blocking port 4. During the
cross-over transition, all ports
are open. The spring chamber
for this valve is vented to port 5.
Features
Hardened, ground and honed
sleeve and spool for low
internal leakage.
