Flow is blocked from 1 to 2 until pressure increases to meet the selected valve setting,  lifting the poppet from its seat and allowing relief flow through port 2 to tank. Pressure at
port 2 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.
