Series S and SM accessory valves are two-position,
three way selector valves. They are designed for
directing flow from one single pump to one, or the
other of two separate hydraulic lines. An example of
this is the operation of two single-acting cylinders,
Series H and HM accessory valves are two-position,
three way selector valves. They are designed to be
used with a three-position, four way valve to provide a
float or free-wheeling condition. Application examples
include plows, loaders, and certain winches.
All four versions of this valve should be shifted prior to
the application of pressure. The flow forces might
make this valve difficult to shift under normal operating
Flow enters the valve at the inlet port. When the lever
is pushed in, the spool shifts allowing inlet flow to
reach the work port furthest away from the lever. When
the lever is pulled out, the spool shifts allowing inlet
flow to reach the work port closest to the lever.
