Case 1:
The motor works in braking mode. Required charge pressure at the inlet port is according to
di a gram above.
Case 2:
The motor works in driving mode only. Required back pressure at the outlet port corresponds to
30% of value given in di a gram above, but may not be lower than 2 bar (29 psi).
Case 3:
The motor is used with 2-speed valve. Required char ge pressure at inlet port for valve is according
to diagram below.
