Cartridge Valves - Pressure Control Valves - Pressure relief

VSNG-10A

RE18318-07-01(2023-11-23)
Description

Flow is blocked bi-directionally between 1 and 2 until pressure at either port increases to meet the selected valve setting, lifting the poppet from its seat and allowing relief flow to the opposite port. The unique Bosch Rexroth Oil Control poppet design provides consistent cracking pressures at both ports and enhanced stability at all flows and pressures. Maximum difference for crack pressure in both direction : 10 bar (145 psi)

¹) Measured at 200 bar (2900 psi)

²) Only external seals for 10 valves
