Bleeding of the valve is usually not necessary. However, Bosch Rexroth
recommends bleeding the entire hydraulic system. In this context, the following
has to be observed:
▶ Before actual operation, switch the valve several times at reduced pressure
(50 % operating pressure). This will press out any remaining air from the valve.
NOTICE! Damage to the valve and the system! Do not switch the valve under
operating pressure as long as the system has not been bled.
Check that during operation no hydraulic fluid leaks at the valve or at the
connections.
If possible, check hydraulic functions in a controlled way and at low pressure.
Observe the operating instructions of the hydraulic system into which the valve is
installed.
