Legend Valve 101-111 Brass Ball Valve 4 Inches Fnpt

Product Description

The LEGEND VALVE 101-111 is a full port, manually operated brass ball valve designed for 4-inch pipe systems. It features female NPT connections on both ends and a lever handle for quick quarter-turn shutoff. The valve body and trim are constructed from brass, with a polytetrafluoroethylene (PTFE) seat that provides a reliable low-friction seal across a broad range of media. At 15 pounds, this is a substantial fitting suited for high-flow commercial and industrial plumbing lines where full bore flow capacity is required. Licensed plumbers and pipefitters are the primary installers of valves in this size class.

This valve is suited for 4-inch pipe installations in commercial plumbing, hydronic heating, industrial process lines, and similar systems where unobstructed full port flow is critical. The FNPT x FNPT end connections make it compatible with standard threaded pipe configurations. The lever handle allows fast visual confirmation of valve position open or closed. This size range is common in mechanical rooms, main service lines, and large-diameter distribution headers.

Installation Notes

Installation of 4-inch threaded ball valves is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the system fully before removing or installing any valve. Apply appropriate thread sealant or PTFE tape to NPT threads per the applicable plumbing code, such as the IPC or local amendments. Do not over-torque the valve body during assembly, and verify valve orientation and handle clearance before returning the system to service.
