Legend Valve 116-206 Flanged Check Valve 6 Inch 125 Psi

Product Description

The LEGEND VALVE 116-206 is a flanged inline check valve designed for 6-inch pipe installations in commercial and industrial piping systems. Built with a cast iron body, this valve allows flow in one direction and prevents backflow without requiring manual operation. It carries a working steam pressure rating of 125 psi and a maximum working pressure of 200 psi, making it suitable for demanding service conditions. At 150 pounds, this is a heavy-duty component intended for permanent installation by licensed pipefitters or plumbers working on large-diameter systems. The MSS SP-71 standard compliance confirms it meets industry requirements for swing check valves.

This valve is suited for inline installation on 6-inch flanged pipe runs in commercial plumbing, industrial process piping, HVAC hydronic systems, and water service applications. The flanged end connections allow for bolted installation directly between mating flanges, making it practical for systems that require periodic removal for inspection or service. Its high maximum temperature rating of 450 degrees F extends its usability into steam and high-temperature hot water applications where standard valves would not qualify.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the International Plumbing Code and ASME B31.1 or B31.9 where applicable. Isolate and fully depressurize the system and allow any heated fluid to cool before removing flanges or installing this valve. Verify flange bolt pattern, gasket selection, and flange rating are compatible with system operating conditions prior to installation. At 150 pounds, appropriate lifting equipment and a second technician are recommended for safe handling during installation.
