1) At 80% of pressure setting

2) Only external seals for 10 valves

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 2 to tank. Pressure at

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. A hardened seat is

provided for increased durability in high-pressure, high-cycle

applications.

Note: the pressure setting must be done after installation, because

the spring cannot be compressed while the cartridge is out of the

cavity. For the same reason the threaded adjuster must be fully

released prior to unscrewing the cartridge from the cavity.
