Brass Faucet Cartridge Valve Core

Brass Faucet Cartridge Valve Core (20-Spline)

     Brass Faucet Cartridge Valve Core is a precision-engineered internal component designed for water faucets and shower mixers. Built for smooth operation and long service life, this cartridge controls water flow and temperature while ensuring reliable sealing performance.
Featuring a 20-tooth spline stem, it provides a secure and accurate connection to standard faucet or shower handles, delivering consistent torque transfer and precise control.

Manufactured from high-quality brass, this valve core offers excellent resistance to wear, corrosion, and pressure fluctuations, making it suitable for both residential and commercial plumbing systems.

Material & Manufacturing Process

This cartridge valve core is produced from premium brass alloy, selected for its durability, machinability, and hygienic properties for water applications.

Key manufacturing processes include:

• CNC Turning for precise outer diameter, threads, and stem geometry

• CNC Milling to form internal features and water flow windows

• Spline Machining (20 teeth) for accurate handle engagement

• Thread Cutting for secure installation into valve bodies

• Deburring & Polishing to ensure smooth surfaces and sealing reliability

• Assembly with Sealing Elements (such as O-rings) to prevent leakage

These processes ensure stable performance, dimensional accuracy, and long-term reliability.
