A spring-centered, spool-type, closed-in-neutral,3-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 HS50-43 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 has a spring-centered spool, and is closed in neutral position.
• Hardened spool and cage for long life.
• Industry-common cavity.
