Nachi SWM-G02 Series Solenoid Valve | SWM-G02-C4-D12-30-S003 | Push-Pull Coil Valve

The SWM-G02 Series from LIC Hydraulic is a highly specialized Push-Pull Coil Solenoid Valve engineered for applications where space is at a premium and reliability is critical. Unlike standard bulky directional valves, the SWM series (including models like SWM-G02-C4-D12-30-H006) features a streamlined actuator design that provides the same powerful shifting force in a significantly smaller footprint. Fully compliant with ISO 4401-03 (G02) mounting standards, it is the perfect solution for modern mobile and industrial systems. We provide 100% drop-in replacements that match original Nachi electrical and hydraulic performance curves.

Technical Highlights

• Size: ISO 4401-03 (Size 6).

• Coil Voltage: D12 (12V DC) and D24 (24V DC) available.

• Actuation: Single-coil push-pull or dual-coil compact configurations.

• Max Pressure: Continuous duty up to $25\text{ MPa}$ ($3625\text{ psi}$).

Core Advantages

• Ultra-Compact Footprint: The unique solenoid housing allows for close-coupled manifold mounting, significantly reducing the overall size of the hydraulic control block.

• Built for Mobile Environments: With its robust vibration-resistant coil and high-ingress protection rating, the SWM-G02 is designed to thrive in the harsh environments of construction and agricultural machinery.

• Reliable Shifting Response: The low-friction spool design combined with high-force solenoids ensures crisp and repeatable switching, even when used with higher viscosity hydraulic fluids.

• Durable Wet-Pin Construction: The armature is immersed in hydraulic oil, which dissipates heat more effectively and provides internal lubrication, leading to a service life of millions of cycles.

Expert Maintenance Tips

• Electrical Polarity: For push-pull single-coil models, ensure the controller is compatible with the polarity-reversal logic required to switch the valve positions.

• Manual Override: Use the integrated manual push-pin for system testing or emergency operation, but ensure the area is clear of debris to prevent the pin from sticking in the actuated position.

• Mounting Torque: When installing on a manifold, tighten the four M5 bolts to the specified $5\text{–}7\text{ Nm}$. Over-tightening can slightly distort the valve body, leading to spool binding.
