Initial Fill
With the lever released and the system pressurized, product enters Port B
and fills Chamber B.
Lever Depresssed
When the lever is depressed, the slide valve moves to allow product
to enter Port A and fill Chamber A. At the same time the slide valve
aligns Port B with Port D. This allows product to flow
from Chamber B via Port B and into Port D to discharge.
Lever Released
When the lever is released, the slide valve moves to allow product to enter Port B
and fill Chamber B once again. At the same time the slide valve aligns Port A with Port D.
Product from Chamber A flows via Port A into Port D to discharge.
