SECTION III USE
Nomenclature
Directional control valve:
A valve that can be operated to control the flow of oil from a pressurised
circuit to an outlet port. There are three main types of directional control
valve: SINGLE-ACTING (no longer used), DOUBLE-ACTING and
DOUBLE/SINGLE-ACTING.
Double-acting control valve:
When the control lever is moved in one
direction, the control valve spool shifts to
allow pressurised oil to flow out through one
port and return through a second port. When
the control lever is moved in the opposite
direction, the direction of flow is reversed.
The control lever has 3 positions: pressure
port 1, neutral 0, pressure port 2.
Double/single-acting control valve:
This valve is like the double-acting valve described above, but can be
converted into a single-acting valve by way of a screw. When operating in
single-acting mode, the valve is connected to the implement by a single
hose connected to the pressure port 1; this hose serves as both the
pressure and return line (when the control lever is in the “return” position).
The control lever still has 3 positions: pressure 1, neutral 0 and return.
