Watts 123477 Full Port Ball Valve 3/4 in Sweat 600 Psi

Product Description

The WATTS 123477 is a 3/4-inch, 2-piece full port lead free ball valve designed for commercial and industrial fluid and gas control. Built with a lead free brass body and solder (sweat) end connections, it handles water, oil, and gas service up to 600 psi WOG and 150 psi WSP. The valve features a chrome plated lead free brass ball, virgin PTFE seat, and a bottom-loaded blowout proof stem. A fluorocarbon elastomer stem O-ring prevents stem leaks, and an adjustable stem packing gland with packing nut allows field adjustment of stem sealing. A cap and chain are included to protect the open port when needed.

This valve is suited for commercial plumbing, mechanical rooms, industrial process lines, and HVAC hydronic systems where a reliable full port shutoff is required. Full port design means minimal pressure drop across the valve, making it appropriate for flow-critical applications. The sweat end connections suit copper pipe installations common in commercial water distribution, oil service, and gas piping systems. Licensed plumbers and pipefitters are the primary installers in both new construction and retrofit applications.

Key Features

• Lead free brass body meets lead free drinking water standards
• Full port design minimizes flow restriction and pressure drop
• Chrome plated lead free brass ball for corrosion resistance and long service life
• Virgin PTFE seat with thrust washer for low-torque, reliable shutoff
• Blowout proof bottom-loaded stem for safety under pressure
• Fluorocarbon elastomer stem O-ring prevents stem leakage
• Cap and chain included for open-port protection

Compatibility

Designed as an OEM-style lead free replacement ball valve for 3/4-inch copper sweat connections in commercial and industrial water, oil, and gas piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and IFGC requirements where gas service applies. Shut off system pressure and drain the line before soldering sweat connections to avoid heat damage to the PTFE seat and elastomer O-ring components. Allow the valve body to cool fully before pressurizing the system and testing for leaks. Verify pressure rating compatibility with the installed system before placing the valve in service.
