Instruction
The lowest controlling pressure is 1.6MPa. Working environment:
When the oil runs reversely, the reverse outlet is the direct
cylinder. If there is back pressure P2 at the reverse outlet, the
lowest controlling pressure should be PK=1.6+P2.
The lowest controlling pressure only opens the small valve. If the
flow is steady, the big valve can' t be opened. If increase the
controlling pressure, the big vale can be full opened.
