MLV9-12-F - Directional Valve
Manual lever valve, spool
60 L/min (15.9 USgpm) • 210 bar (3000 psi)
Description
This is a lever operated 4 way
3 position direct acting spool
type directional valve. Spring
centered with ports 2 and 4 to
tank and port 2 blocked. This
valve can easily be installed
into a manifold simplifying
the design and removing leak
points.
Operation
In the center position, port 1,
port 2, and port 4 are open to
each other while port 3 is
blocked. In position 1, flow is
directed from port 3 to port 4
and from port 2 to port 1.
In position 2, flow is directed
from port 3 to port 2 and from
port 4 to port 1.
Features
Hardened, ground and honed
working parts to limit leak-
age and prolong life. Compact
design with a low pressure
drop. Handle position fully
adjustable.
