Brass Gas Ball Valve, DL 1150 one half inch, QR11F 16T DN15, 0.59 inch nominal diameter, 232 psi nominal pressure, internal thread, external thread

Product Characteristics Durability : Made of brass and copper alloy, the valve is robust and corrosion-resistant, ensuring a long service life in gas supply systems. Sealing Performance : PTFE sealing material provides reliable leak-proof performance, critical for safe gas handling and preventing hazardous leaks. Easy Operation : The lever handle allows for quick on/off control, simplifying gas flow regulation in residential and commercial gas systems. Versatility : Specifically designed for gas media, making it ideal for natural gas and liquefied petroleum gas supply in homes, restaurants, and small commercial facilities. How to Use Ensure the valve and mating gas pipes have compatible internal/external threads. Apply thread sealant or gas-specific Teflon tape to the threads 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 gas flow: rotate 90 degrees to fully open or close. Regularly inspect the valve for leaks (using soapy water to detect bubbles), 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 with soapy water to ensure it remains leak-proof in gas systems.
