903 Series Brass Float Ball Valve, KXF X3 DN15, 0.59 inch nominal diameter, 232 psi nominal pressure, NPT external thread

Product Characteristics Durability : Made of brass and copper alloy, the valve is robust, corrosion-resistant, and designed for long-term use in cold water storage scenarios. Sealing Performance : Brass sealing surfaces provide reliable leak-proof performance, maintaining water level control integrity under operational pressure for cold water. Automatic Operation : The float ball mechanism automatically opens and closes the valve based on water level, ensuring consistent water levels in tanks and reservoirs. Versatility : Suitable for cold water systems in tanks, reservoirs, and water towers, making it ideal for residential, commercial, and light industrial water storage applications. How to Use Ensure the valve and mating pipes have compatible NPT external threads. Install the valve at the water inlet of the tank or reservoir, positioning the float ball in the water chamber. Adjust the float arm length to set the desired water level (longer arm for higher level, shorter for lower). Test the valve by filling the tank; the float ball should rise and close the valve when the set level is reached, and open when the level drops. Regularly inspect the float ball, arm, and valve body for damage, corrosion, or misalignment, and replace components if necessary. Maintenance Tips Clean the float ball and valve internals periodically to remove debris that may interfere with movement or sealing. Check the valve’s sealing components regularly to ensure they remain effective for cold water applications. Test the valve’s automatic operation regularly to ensure it maintains the correct water level without leaks.
