Principle features
When the coil is de-energized, SZ 212 prevents the flow of oil to ③ and allows the flow of oil from ② to ① or from ④ to ①. When coil 1 is energized, oil can flow from ③ to ④ and from ② to ①. When coil 2 is energized, fluid can flow from ③ to ② and from ④ to ①. In an oil circuit where the flow rate at the working port is uneven due to the cylinder volume ratio, a large amount of return flow should be directed to port ②. Although port ① can be fully pressurized, it is not used as a 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). Pushing the knurled handle controls the function of coil 1 (S1) or pulling the knurled handle controls the function of coil 1 (S1).
