YUKEN DSHG-03-3C4-T-D24-N1-12 Valve

Application scenarios-Machine tool hydraulic system: used for clamping cylinder or tool magazine tool change control.-Injection molding machine: driving direction switching of small flow actuators.-A closed-loop system that requires leak prevention (due to its central closure).

-DSHG: Series code, representing the three position four-way electromagnetic directional valve of Oil Research.
-03: Valve diameter specification (03 corresponds to NG6, with a nominal diameter of approximately 6mm).
-3C4: Valve core function symbol, indicating a three position four-way closed type (specific function needs to be checked in the sample, commonly known as closed A/B ports and connected P/T ports).
-T: Spring centering method (T represents spring reset, and the center position of the three position valve is maintained by the spring).
-D24: Coil voltage specification (DC24V).
-N1: Electrical connection method (N1 may represent a standard socket type junction box).
-12: Design code or version number (specific improvement details should refer to the manufacturer's documentation).

-Pressure rating: Typically, the maximum working pressure is 21MPa (depending on the sample).
-Flow range: Approximately 20-30 L/min under NG6 diameter (depending on pressure difference).
-Sealing material: NBR or FKM (fluororubber) can be selected to adapt to different fluid temperatures.
Detailed explanation of valve core function (3C4)
-Median function: A and B ports are closed, P → T port is unloaded (energy-saving design), suitable for scenarios where the actuator needs to maintain its position and the system is unloaded.
-Reversing characteristics: When the electromagnetic iron is energized, P → A/B, T → another cavity; After power failure, the spring returns to the neutral position.
