HS10-42 Valve

SYMBOL:

Transition:

DESCRIPTION
A spool-type, closed in transition, 2-position, 3-way hot oil shuttle valve, which may be
used on hydrostatic transmissions to direct charge pump oil to a heat exchanger or to tank.

OPERATION
With internal piloting at port 1, 2 or 4, the HS10-42 / HS50-42 will direct oil flow from the port
opposite of the port piloted to port 3, thus removing oil from the low-pressure side for cooling
or filtration purposes.
The valve is springless, relying solely on the internal pilot pressure signal to shift to either side.
Flow paths are closed in transition.

FEATURES
• Hardened parts for long life.
• Industry-common cavity.
