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 HS52-42 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.
