Logic element, pressure
compensator combination type
Common cavity, Size 12
Flow is normally allowed from 4 to 3. When pilot pressure at 1 rises
above the combined pressure of the spring bias, plus pressure at 4,
the valve shifts to block flow between 3 and 4, while diverting flow
from 1 to 2. A constant pressure drop is maintained across a fixed
(or variable) orifice upstream of 4 when installed and piloted per the
diagram above. In this case, flow priority is given to 3, with flow in
excess of the orifice differential requirement being by-passed to 2.
