HS52-43 Low Side (Hot Oil) Shuttle, (HS52-43)
A spring centered, spool-type, closed in neutral, 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, the HS52-43 will direct oil from the port opposite of the piloted port to port ➂, thus removing oil from the low-pressure side for cooling or fi ltration purposes. The valve has a spring-centered spool, and is closed
in neutral position.
Product Features
