5 month ago
Product details
I. Product Overview
TheSWH-G02-C2B-D24-20is an electromagnetic directional control valve manufactured byNorthman (Taiwan)and other industrial suppliers. It is designed for fluid control in automated systems, enabling precise switching of hydraulic or pneumatic pathways in industrial applications.
II. Key Features
1. Oil-Immersed Design
• The solenoid is submerged in hydraulic oil to reduce noise and friction between the spool and seals, extending service life.
• Damping design minimizes shifting impact, enhancing system stability.
2. High-Pressure Adaptability
• Maximum operating pressure:315 bar (31.5 MPa), suitable for high-pressure hydraulic systems.
• Metal alloy valve body with optimized internal flow channels to reduce pressure loss.
3. Energy Efficiency & Durability
• High energy utilization efficiency lowers operational costs.
• Optimized temperature rise control reduces seal aging, saving maintenance expenses.
4. Modularity & Interchangeability
• Interchangeable components (spool, coil, ports) simplify repairs and functional upgrades.
• Mounting face complies with international standards:ISO 4401, CETOP, DIN24340, NTPA.
5. Protection Rating
• Corrosion-resistant valve body withIP65protection against dust and liquid ingress.
• Waterproof and dustproof electrical connections for harsh environments.
III. Technical Specifications
• Model: SWH-G02-C2B-D24-20
• Mounting Type: Plate-mounted
• Port Size: Size 6 (some series support Size 10)
• Coil Voltage: DC24V (AC options available: A220V, A240V)
• Wiring Method: Plug-in connector with indicator light (identified by "20" in model)
• Operating Pressure Range: 0.5–25 MPa (up to 31.5 MPa in specific applications)
• Media Temperature: -10°C to 80°C
• Port Thread: G, M, or other standard options
IV. Functions & Applications
1. Typical Use Cases
• Hydraulic control systems in construction machinery (e.g., excavators, cranes).
• Pneumatic actuators in automated production lines (e.g., robotic arms, conveyors).
• Directional switching devices for material handling equipment (e.g., valve control, diverters).
2. Extended Functions
• Connect hydraulic breakers via OPTION valves for single-circuit operation.
• Support automatic travel pressurization to improve traction on challenging terrain.
V. Structural Design
1. Valve Body
• Compact design with resin sand casting and ultrasonic cleaning for reliability.
• Precision-ground spool with high-accuracy guiding for smooth operation.
2. Solenoid Coil
• Fully enclosed encapsulation with built-in thermal protection for continuous duty.
• Fast response time (customizable based on model selection).
VI. Maintenance & Troubleshooting
1. Regular Inspections
• Electrical Connections: Ensure coil wiring is secure to prevent loosening or short circuits.
• Seal Integrity: Check for leaks at valve ports and replace aged seals promptly.
2. Common Faults & Solutions
• Slow Actuator Movement: Verify pilot pressure, spool binding, or spring failure.
• System Overheating: Inspect negative flow relief valves for blockage or incorrect pressure settings.
• Failed Shifting: Clean throttle orifices or replace damaged solenoid coils.
3. Modular Maintenance
• Key components (e.g., spool, coil) can be replaced independently, reducing repair costs.
