Watts 547102 1/2 Inch Full Port Threaded Brass Ball Valve

Product Description

The WATTS 547102 is a full port threaded brass ball valve designed for reliable shutoff and flow control in residential and commercial piping systems. Built from solid brass, this valve delivers low flow restriction thanks to its full port design, meaning the internal bore matches the pipe diameter for unrestricted flow. It carries CSA, UL, and FM certifications, making it suitable for installations that require listed components. Licensed plumbers and pipefitters are the primary installers of this valve in water supply, heating, and general service piping applications.

This valve is sized at 1/2 inch and uses threaded end connections, making it straightforward to install in standard threaded pipe configurations. It is well suited for residential water supply lines, hydronic heating systems, commercial plumbing distribution, and light industrial service lines where a reliable manual shutoff is required. The full port design is particularly useful in systems where pressure drop must be minimized across isolation points.

Key Features

• Full port bore for unrestricted flow and minimal pressure drop
• Brass construction for corrosion resistance in water and hydronic service
• Threaded end connections for standard pipe installation
• CSA, UL, and FM certified for use in listed and code-required applications
• 1/2 inch size fits common residential and light commercial piping

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 1/2 inch threaded pipe systems in plumbing, hydronic heating, and general service applications.

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 the water supply and relieve system pressure before removing or installing this valve. Use appropriate thread sealant or PTFE tape on threaded connections to ensure a leak-free joint. Do not over-tighten threaded fittings, as this can damage the valve body or adjacent pipe threads.
