Brass Two Piece Ball Valve, DN100, 4 in Nominal Diameter, NPT Internal Thread

Product Characteristics Durability : Made of HPb59-1 brass with forging process, the valve is robust, corrosion-resistant, and meets GB/T8464-2008 national standards, ensuring long-term reliability in diverse water handling scenarios. Structural Integrity : Thickened valve body and two-piece design provide excellent pressure resistance, making it explosion-proof and stable under medium-pressure conditions. Sealing Performance : Brass sealing surfaces offer reliable leak-proof performance, maintaining system integrity for water supply in homes, hotels, and factories. Easy Operation : The lever handle allows for quick on/off control, with fast opening/closing, light operation, and low fluid resistance, simplifying flow regulation in various piping systems. 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 to ensure it remains leak-proof in various water systems.
