American Granby CVNL100BS 1 in. No-Lead Brass Spring Check Valve
Product Overview
The American Granby CVNL100BS is a 1 in. spring check valve designed to help maintain one-way flow in compatible well pump, pressure tank, plumbing, and water-system piping. When system pressure changes or a pump shuts off, the spring-loaded internal assembly closes to help limit reverse movement through the line. This can support more stable pump operation and help protect connected equipment when the valve is correctly selected and installed.
The valve uses a no-lead brass body, female pipe-thread connections, stainless steel internal trim, and a Buna-N O-ring. Its 200 PSI rating and listed gas, oil, and water media compatibility make it suitable for a range of properly approved applications. Confirm media, pressure, flow direction, and local requirements before installation.
