Description
Flow is blocked from 1 to 2 until pressure increases to meet the
selected valve setting, lifting the conical, pilot-stage poppet 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. Pressure
at 2 is additive to the relief setting of the valve. Pilot operation is
protected from contamination by a filter screen at the bottom of the
main piston.
