DSV4-12 - Shuttle Valve
Sprung centered, open or closed center spool type shuttle valve
113 L/min (29.9 USgpm) • 350 bar (5000 psi)
Description
This is a 3-way 3-position,
sprung centered, open or
closed center spool type hot oil
shuttle valve for transmission
applications. This is usually built
into manifolds containing other
transmission components such
as cross line relief valves and
purge reliefs.
Operation
When the spring bias is
overcome at port 2, the flow is
directed from port 4 to port 3
while closing port 2.
When the spring bias is
overcome at port 4, the flow is
directed form port 2 to port 3
while closing port 4. This valve
is available in both a closed and
open center spool
configuration.
Features
Hardened, ground and honed
working parts to limit leakage
and prolong life. The valve
should be fitted into a blind
C-10-4 cavity or a standard
body with port 1 plugged.
Several switching pressures
available. Compact design with
a low pressure drop.
