MLV9-12-A - 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. Sprung
centered with port 3 open to
port 1 (Tank). Ports 2 and 4
blocked. This valve can easily
be installed into a manifold
simplifying the design and
removing leak points.
Operation
In the center position, this
valve allows flow from port 3 to
port 1 and blocks ports 2 and 4.
In position 1, flow is directed
from port 3 to port 2 and from
port 4 to port 1. In position 2,
flow is directed from port 3 to
port 4 and from port 2 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.
