Nibco NL9901B Ball Valve 1-1/4 in Fnpt Full Port 600 Psi

Product Description

The NIBCO NL9901B is a 2-piece, full-port ball valve in the T-685-80-LF series, built for potable water and plumbing systems where lead-free materials are required. The body, ball, and stem trim are all silicon bronze, providing corrosion resistance in water service applications. Softgoods are EPDM and virgin PTFE, suited to water media at pressures up to 600 psi. The valve is lever-operated with a 1-1/4 inch orifice and FNPT connections on both ends. Licensed plumbers and mechanical contractors install this valve in commercial and residential piping systems. It complies with California Health and Safety Code Section 116875 for drinking water applications.

This valve is sized at 1-1/4 inches nominal and is appropriate for shut-off service in potable water distribution, hydronic heating lines, and general plumbing systems where a full-bore, low-restriction shutoff is needed. The full-port design minimizes pressure drop across the valve, making it suitable for flow-critical applications. The T-685-80-LF series is a lead-free product line intended for installations in jurisdictions that enforce lead-free requirements for drinking water contact components.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the supply line and drain the system before removing or installing the valve. Apply thread sealant or PTFE tape to male threads per local code requirements before making up the connection.
