Legend Valve 251BVLF Boiler Drain Valve 1/2 Inch Mip

Product Description

The LEGEND VALVE 251BVLF is a quarter-turn boiler drain valve with a 1/2 inch male iron pipe (MIP) connection. Boiler drain valves are installed at low points in hydronic heating systems, water heaters, and supply lines to allow controlled drainage and system servicing. The quarter-turn ball-style operation provides fast, positive shutoff with minimal effort. At 0.42 pounds, this is a compact, lightweight fitting suited for residential and light commercial plumbing applications. Licensed plumbers and HVAC technicians are the primary installers of this type of valve.

This valve is used wherever a reliable drain point is needed on a boiler, water heater, or hydronic piping system. Typical applications include boiler blowdown ports, hose bib drain connections on supply and return lines, and low-point service drains on closed-loop systems. The 1/2 inch MIP thread is a common connection size found throughout residential and commercial hydronic and domestic water systems, making this a standard service and replacement fitting for plumbing professionals.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing codes. Shut off the water supply and relieve system pressure before removing or installing any drain valve. Apply thread sealant tape or pipe dope to MIP threads before tightening to ensure a leak-free seal. Do not overtighten threaded connections, as this can damage valve bodies or mating fittings.
