HS10-42 Low Side (Hot Oil) Shuttle, Springless (HS10-42)
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.
Product Operation
With internal piloting at port ➀, ➁ or ➃, oil will flow 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.
Product Features
• Hardened parts for long life.
• Industry common cavity.
