Watts 450113 Lead Free Bronze Ball Valve 1-1/2 in

Product Description

The WATTS 450113 is a 2-piece, full port, lead-free bronze ball valve rated for 600 WOG (non-shock) and 150 WSP. It is built for commercial and industrial plumbing systems where reliable shut-off and minimal pressure drop are required. The 1-1/2-inch socket (solder) end connection suits copper piping installations. A chrome-plated brass ball and virgin PTFE seat and stem packing deliver consistent sealing performance across the full rated pressure and temperature range. The blowout-proof stem adds a layer of safety in pressurized service. Licensed plumbing contractors and mechanical contractors are the primary installers of this valve in commercial and industrial settings.

The WATTS 450113 is suited for commercial and industrial piping applications handling the full range of liquids and gases within the rated limits. The solder end connection makes it a direct fit for copper pipe systems in mechanical rooms, HVAC hydronic circuits, process piping, and general building plumbing. Its full-port orifice maintains line velocity and minimizes pressure drop, which is especially important in flow-critical hydronic and process systems.

Key Features

• Full-port orifice minimizes pressure drop across the valve
• Lead-free construction with NSF-372 certification for potable water compliance
• Blowout-proof stem design for safe operation under pressure
• Chrome-plated brass ball with virgin PTFE seat and stem packing for long service life
• 2-piece bronze body rated 600 WOG / 150 WSP
• 1-1/2-inch socket (solder) end connection for copper pipe systems

Compatibility

Designed as an OEM-style full-port ball valve for 1-1/2-inch copper pipe systems in commercial and industrial plumbing and hydronic applications requiring lead-free, NSF-372 compliant 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 allow all piping to cool completely before soldering the socket connections. Avoid applying excessive heat directly to the valve body during soldering, as overheating can damage the PTFE seat and packing seals. Verify flow direction and system pressure ratings before returning the line to service.
