HS52-43 Valve

HS52-43 Valve symbol

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 HS52-43 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.

Operating Pressure: 345 bar (5000 psi) when used in ductile iron or steel body
