The A.Y. MCDONALD 5424-018 is a full port ball valve with a sweat connection, sized at 2.5 inches for use in residential and commercial plumbing and hydronic systems. Full port design means the valve bore matches the pipe interior diameter, minimizing pressure drop and flow restriction across the valve. Weighing 6.51 pounds, this is a robust valve suited for isolation, shutoff, and flow control applications. Licensed plumbers and pipefitters are the primary installers of this valve in copper piping systems where a reliable, low-restriction shutoff is required.
This 2.5-inch sweat-connection ball valve is well suited for copper pipe installations in commercial and residential hydronic heating systems, chilled water lines, domestic water distribution, and general plumbing applications. The sweat-end configuration requires soldering to standard copper tubing, making it a common choice for new construction and retrofit projects where copper is the specified pipe material.
Designed as an OEM-style replacement or new-installation ball valve for 2.5-inch copper pipe systems in residential and commercial plumbing and hydronic applications.
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 water system completely before cutting into existing piping. Use proper soldering flux and lead-free solder when sweating connections to comply with current potable water regulations. Allow solder joints to cool fully before pressurizing the system and checking for leaks.
