Media & Seal Material Selection
|
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.
Our Advantages:
This 2WBY solenoid valve is designed for durability, stability, and ease of installation, with the following key highlights:
✅ Solid Construction & Long Service LifeBuilt with an all-brass valve body and all-copper coil, paired with NBR (nitrile rubber) seals for excellent sealing performance. It ensures long-term stable operation and supports continuous power-on without coil burnout.
✅ Thoughtful Details for Hassle-Free InstallationThe valve body features a clear flow direction mark, and the lead wires come with rubber protection. The threads are well-defined to prevent leakage, making installation straightforward even for beginners.
✅ Wide Compatibility & Versatile ApplicationsAvailable in common port sizes like DN15/DN20, with a pressure rating of 0-1.0 MPa. Suitable for low-viscosity media such as water and air, and the standard AC220V specification meets most household and industrial application needs. |
