Description
Flow is blocked from 1 to 2 until pressure increases to meet the
selected valve setting, lifting the pilot-stage ball check from its seat.
This action exhausts oil above the main-stage piston (spool type),
allowing it to shift and provide relief flow through 2 to tank. The valve
applies a balanced piston design allowing consistent relief operation
at the valve setting independent of back-pressure at 2.
