Two piece ball valve, HK 564 DN50, 1.97 inch nominal diameter, 232 psi nominal pressure, NPT internal thread

Product Characteristics Durability : Made of brass and copper alloy, the valve is robust and corrosion-resistant, ensuring a long service life in water and heating system applications. Sealing Performance : PTFE sealing material provides reliable leak-proof performance, even under medium-pressure and temperature conditions for water and heating fluids. Low Resistance : The two-piece design offers minimal flow resistance, ensuring efficient fluid passage in plumbing systems. Versatility : Specifically designed for plumbing accessories, making it ideal for residential and commercial water heating and plumbing 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 water heating systems, to ensure it remains leak-proof.
