Description
Flow is blocked from 2 to 1 until pressure increases to meet
the selected valve setting, lifting the poppet from its seat
and allowing relief flow through port 1 to tank. Pressure at
port 1 is additive to the relief setting of the valve. The unique
Bosch Rexroth Oil Control poppet design provides enhanced
stability at all flows and pressures.
