Brass Ball Valve, DN20, 0.79 in Nominal Diameter, 20 bar Nominal Pressure, NPT Internal Thread

Product Characteristics Durability : Made of high-quality brass (59% copper content) with hot forging process, the valve is robust, pressure-resistant, and explosion-proof, ensuring a long service life in diverse fluid and gas handling scenarios. Sealing Performance : Copper alloy sealing material provides reliable leak-proof performance, even under high-pressure and temperature conditions for water, gas, and non-corrosive liquids. Easy Operation : The lever handle allows for quick on/off control, simplifying flow regulation in piping and gas systems. Versatility : Suitable for water, non-corrosive liquids, and civil gases like natural gas and liquefied petroleum gas, making it ideal for residential, commercial, and industrial 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 high-pressure or gas systems, to ensure it remains leak-proof.
