4. Selection Guide
• Voltage Matching: Ensure coil voltage matches the power supply (e.g., AC220V for cost-effective systems, DC24V for safety-critical applications).
• Power Requirements:
• Use low-power coils (17W) for systems up to 3000 psi (210 bar).
• Use high-power coils (25W) for systems up to 5000 psi (350 bar).
• Environmental Considerations:
• Choose explosion-proof coils for hazardous areas.
• Opt for IP69K-rated coils for high-pressure washdown environments.
5. Installation & Maintenance
• Installation:
• Ensure proper torque (25–30 lbf·ft) for mounting.
• Verify alignment with valve body to prevent leaks.
• Maintenance:
• Regularly inspect coil insulation and connections.
• Clean coils to prevent oil contamination and overheating.
• Troubleshooting:
• Check for voltage drops or loose connections if the coil fails to activate.
• Replace damaged coils promptly to avoid valve malfunctions.
