Brass Float Valve Threaded Water Level Control Valve (CE Certified)
The Brass Float Valve is a precision-engineered automatic water level regulator, crafted from high-performance forged CW614N and HPb57-3 brass alloys. Its buoyancy-driven floating ball mechanism automatically opens/closes to maintain preset liquid levels, preventing overflow and dry running in tanks, boilers, and plumbing systems. Available in 1/2" to 2" BSP/NPT threads with CE/ISO9001 certification, it offers superior machinability, corrosion resistance (suitable for fresh/sea water), and pressure tolerance (up to 16 bar), making it ideal for residential, commercial, and industrial fluid control scenarios.

- Recommended Products
- Check for leaks regularly.
- Clean exterior with mild detergent.
- If the valve becomes stiff, disassemble and lubricate with plumbing-grade lubricant.
- Avoid abrasive cleaners.
