Watts 123474 Full Port Ball Valve 0.5 in Ips Lead Free

Product Description

The WATTS 123474 is a 2-piece, full port, lead free ball valve designed for controlling flow in commercial and industrial piping systems. Built around a lead free brass body with a machined chrome plated lead free brass ball, this valve handles the full range of liquids and gases encountered in trade work. The pressure rating is 600 psi WOG (water, oil, gas) and 150 psi WSP (working steam pressure). Key construction details include a bottom-loaded blowout proof stem, virgin PTFE seat, fluorocarbon elastomer stem O-ring, thrust washer, adjustable stem packing gland, and a cap and chain assembly to protect the port opening when the valve is operated as a drain or test point.

This valve is suited for commercial plumbing, mechanical, and industrial piping applications where full flow capacity and lead free compliance are required. The 0.5 inch IPS end connections make it a standard drop-in fit for half-inch threaded piping systems. The steel handle allows quick quarter-turn operation. The included cap and chain keep the outlet protected during normal service, which is common in boiler drains, test tees, and isolation configurations found in commercial and light industrial mechanical rooms.

Key Features

• Lead free brass body and ball construction meets lead free compliance requirements for potable water systems
• Full port design minimizes flow restriction and pressure drop across the valve
• Bottom-loaded blowout proof stem provides a secondary safety barrier against stem ejection under pressure
• Virgin PTFE seat and fluorocarbon elastomer stem O-ring deliver reliable sealing across a wide service range
• Adjustable stem packing gland and packing nut allow field adjustment to address minor stem leaks without valve replacement
• Cap and chain included to protect the outlet port during service

Compatibility

Designed as an OEM-style replacement or new-installation valve for 0.5 inch IPS threaded piping systems in commercial and industrial water, oil, and gas service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IFGC requirements for gas service. Isolate and depressurize the line completely before installation or removal. Apply thread sealant or PTFE tape appropriate for the service medium to all threaded connections. For gas service, verify all connections with an approved leak detection method before returning the system to operation.
