HS10-42 Valve

HS10-42 Symbol

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 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.

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