Working principle:
When the power is off, the KSV10-47BL-0-N cylinder oil port is connected, and ③ and ① are connected at the same time. When coil 1 is energized, it allows oil to flow from ③ to ④, and from ② to ①. When coil 2 is energized, oil can flow from ③ to ②, and from ④ to ①. In the oil circuit where the flow rate of the working oil port is unbalanced due to the area ratio of the oil cylinder, the return oil with a larger flow rate should be directed into the oil port ②. Although port ① can be fully pressurized, it is not used as the valve inlet.
How to operate the emergency hand control option: During emergency operation, push the knurled handle to control the function of coil 2 (S2), or pull the knurled handle to control the function of coil 1 (S1).
