Cartridge only
By turning the operator 90°, flow
will be directed between ports
1 and 4 and port 3 to port 2.
During the cross-over transition,
ports 2 and 4 are blocked and
ports 1 and 3 are connected.
Features
Hardened, ground and honed
working parts to limit leakage
and prolong life. Various levers
and knobs available with
and without detent. Working
pressure 350 bar.
