How to Properly Maintain a Double Corner Valve to Extend Its Lifespan

A double corner valve is an essential component in residential and commercial water supply systems. Its dual-outlet design allows simultaneous connections to two appliances (such as a toilet and a washbasin) while providing independent water flow control. Since a double corner valve is in constant contact with water, proper maintenance is crucial for ensuring its longevity and reliability. Below are essential maintenance tips for keeping a double corner valve in optimal condition.

1. Regular Cleaning to Prevent Scale Buildup

Over time, mineral deposits in water can accumulate inside the double corner valve, affecting its water flow efficiency and sealing performance. A cleaning routine every 3-6 months is recommended:

• Shut off the water supply, remove the double corner valve, and wipe it with a soft cloth soaked in vinegar or a neutral detergent.
• For stubborn deposits, soak the double corner valve in a mixture of warm water and vinegar for 30 minutes before wiping.
• Rinse thoroughly with clean water and allow it to dry before reinstalling.
  Chinese faucet factories manufacture double corner valves with smooth, high-quality surfaces that resist dirt buildup, making them easier to clean.

2. Avoid Excessive Force to Protect the Valve Core and Sealing Ring

The double corner valve relies on an internal sealing ring and valve core to control water flow. Excessive force when turning the valve can cause damage to these components, leading to leaks. To extend the lifespan of the double corner valve, always operate it gently.
Chinese faucet factories use high-quality sealing materials and precision-engineered valve cores to ensure long-term leak resistance, even under high water pressure.

3. Regularly Check for Leaks

Sealing rings prevent water leakage in a double corner valve. If drips appear when the valve is closed, the sealing ring may have aged or the connection may be loose. Conduct a sealing check every 6 months and replace any worn sealing rings as needed.
For enhanced sealing, tighten threaded connections and use PTFE tape (thread seal tape) where necessary. Chinese faucet factories rigorously test double corner valves to ensure they maintain excellent sealing performance over time.

4. Prevent Corrosion by Keeping the Surface Dry

Although double corner valves are made from corrosion-resistant materials like brass or stainless steel, prolonged exposure to moisture can still impact their durability. Periodically wiping the valve dry prevents water stains and reduces the risk of long-term damage.
Chinese faucet factories utilize advanced plating and polishing techniques to improve the corrosion resistance of double corner valves, ensuring long-term stability in humid environments.

Conclusion

Proper maintenance and correct usage significantly extend the lifespan of a double corner valve, ensuring stable water flow control. Regular cleaning, gentle operation, corrosion and freeze protection, and periodic sealing inspections all contribute to its optimal performance. Chinese faucet factories manufacture durable and high-performance double corner valves, meeting the needs of global water supply systems.
