Boom-Section-Bypass Valve
The boom bypass redirects the fluid flow for a boom section
to the tank when you turn off the boom section. You can
adjust the boom bypass to ensure that the boom pressure
remains constant no matter how many booms sections are on.

Agitation Valve

This valve is located on the rear of the tank
When agitation is on, the flow is directed through the
agitation nozzles in the tank. When agitation is off, the flow
is directed through the pump suction.

for the agitation circuit. It provides additional flow for the
boom sections.
