Nachi Type SA/SS Solenoid Valve | SA-G01 | SS-G03 | C6 C7Y A3Z C4 | 24VDC 110VAC Hydraulic Control Valve

SA / SS Series Solenoid Directional Valves (G01/G03)

Product Overview: The SA and SS series represent premium solenoid-operated directional valves engineered for precision machine tools, injection molding machinery, and high-load hydraulic power units. The SA series utilizes high-performance AC/DC wet-type solenoids for superior switching stability, while the SS series is renowned for its ultra-long service life and silent operation. This range covers Size 01 (NG6) and Size 03 (NG10) standards, with design codes such as 31, J21, and J22 signifying the latest advancements in energy efficiency and vibration resistance.

Featured models include: SA-G01-C6-D2-31, SS-G03-C7Y-R-D2-31, SS-G03-C5-R-C1-J21, SS-G03-A3Z-R-D2-J22, and SS-G03-C4-R-D2-J22.

Key Technical Advantages:

• Ultra-Long Mechanical Life: Wet-type technology allows the armature to move in oil, eliminating mechanical clatter and achieving a life cycle of tens of millions of shifts.

• Low Power & High Reliability: “D2” (DC24V) and “C1” (AC110V) options are optimized for strong electromagnetic force, ensuring rapid spool shifting even under high pressure.

• Versatile Functions & Options: The “R” designation includes integrated surge absorbers and LED indicators, protecting PLC contacts and simplifying on-site diagnostics.

• High Pressure & Flow Capacity: The G03 frame supports high rated pressures with minimal pressure drop across complex hydraulic circuits.
