Selection Tips
1, Voltage Matching: AC220V is for standard mains power; DC24V/12V are better for industrial control, vehicle, and low-voltage systems. Always confirm the coil voltage to avoid burnout. 2,Temperature Limits: The seal material determines the maximum operating temperature. For example, NBR (80°C max) is not suitable for continuous use in hot water above 80°C, as it will degrade and leak. 3,Media Compatibility: Oily media requires VITON seals, as NBR will swell and fail in oil. Steam applications should use VITON or higher-grade seals. 4,Size Consistency: Always match the valve size to your pipe's nominal diameter. Using a smaller valve will restrict flow and shorten its lifespan.
Supplementary Key Points (3 Points Summary)
✅PTFE Seal UpgradePTFE sealing is newly upgraded, with temperature resistance up to 260℃, excellent resistance to strong acid, alkali and organic solvents, ideal for chemical and high-temperature steam working conditions.
✅Dual Power OptionsIt provides dual power specifications: 22VA/30VA for AC and 17W/24W for DC, matching different coil types and adaptable to customers' various power load requirements.
✅Model Code RuleThe letter X in the model stands for sealing material code: N=NBR, E=EPDM, V=VITON; just replace it directly when ordering.
