Cartridge Valves - Pressure Control Valves - Pressure relief

VSDN-10A

RE18318-03-01(2023-11-22)
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.

¹) At 80% of pressure setting

²) Only external seals for 10 valves
