DIRECTIONAL CONTROLS
HS10-42 Low Side (Hot Oil) Shuttle, Springless
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 ➀, ➁ or ➃, oil will fl ow from the port opposite of the port
piloted to port
➂, thus removing oil from the low-pressure side for cooling or fi ltration
purposes. The valve is springless, relying solely on the internal pilot pressure signal
to shift to either side. The HS10-42 is closed in transition.
FEATURES
• Hardened parts for long life.
• Industry common cavity.
