Relief, direct acting guided

poppet type

Common cavity, Size 08

VSBN-08A 04.11.49 - X - 56 - Z

Description
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.
