Brass Ball Valve, DN40, 1.57 in Nominal Diameter, 16 bar Nominal Pressure, NPT Internal Thread

Product Characteristics Durability : Made of brass and copper alloy with hot forging process, the valve is robust, corrosion-resistant, and features a polished surface treatment, ensuring long-term reliability in diverse fluid handling scenarios. Sealing Performance : Brass sealing surfaces provide reliable leak-proof performance, maintaining system integrity under medium-pressure and temperature conditions for water, non-corrosive liquids, and air. Easy Operation : The lever handle allows for quick on/off control, simplifying flow regulation in industrial and commercial piping systems. Versatility : Suitable for water, non-corrosive liquids, and air in industrial, commercial, and large-scale residential applications. How to Use Ensure the valve and mating pipes have compatible NPT internal threads. Apply thread sealant or Teflon tape to the male threads of the pipe for a secure, leak-proof connection. Screw the valve onto the pipe by hand first, then tighten with a wrench (avoid over-tightening to prevent thread damage). Use the lever handle to open or close the valve: rotate 90 degrees to fully open or close the flow. Regularly inspect the valve for leaks, corrosion, or handle damage, and replace if necessary. Maintenance Tips Periodically lubricate the valve stem (if applicable) to ensure smooth handle operation. Clean the valve exterior and threads to prevent debris buildup and corrosion. Test the valve’s sealing performance regularly, especially in medium-pressure systems, to ensure it remains leak-proof.
