SWH-G02-C6-A220-20 Solenoid Directional Valve 315bar

Product Overview

The SWH-G02-C6-A220-20 and SWH-G02-C4-D12 are SWH-G02 series wet-type solenoid-operated directional valves. Designed for CETOP 03 / ISO 4401 NG6 subplate mounting, they feature a maximum operating pressure of 315 bar and rated flow of 63 L/min. Spool types C6 and C4 provide 3-position functionality with different neutral circuit configurations. These valves offer true interchangeability as drop-in replacements for Yuken DSG-01, Rexroth 4WE6 and equivalent units without manifold modifications. Every valve undergoes precision machining and 100% simulated duty-cycle testing to ensure reliable shifting, low pressure drop and long service life for industrial hydraulic direction control.

Key Technical Advantages

1. Wet-type solenoid design – Oil-immersed coils provide low temperature rise, extended life and quiet operation, ideal for high-frequency shifting.
2. High-pressure high-flow capability – 315 bar operating pressure and 63 L/min flow meet the majority of industrial hydraulic requirements.
3. True interchangeability and standard interfaces – Fully compliant with ISO 4401 NG6 mounting pattern, enabling direct replacement of Yuken, Rexroth and equivalent valves.
4. Precision machining and reliable sealing – High-accuracy spool and body fit delivers low pressure drop and minimal leakage, verified by 100% duty-cycle testing.

Application Areas

Ideal for injection molding machines, die-casting equipment, machine tools, hydraulic power units, mobile machinery, metallurgical plants and any industrial hydraulic system requiring reliable directional control.

Expert Maintenance Tips

Ensure the manifold surface is flat and clean and tighten bolts to the specified torque; confirm voltage match and proper earthing before wiring; maintain fluid cleanliness at 25 μm or better; periodically check solenoid temperature rise and shifting action; after prolonged storage, energize the valve to verify free spool movement.
