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