Legend Valve T-451 3" Brass Swing Check Valve 105-110

3-Inch Brass Swing Check Valve

The Legend Valve T-451 is a 3-inch brass swing check valve designed for plumbing systems that require unidirectional flow control. It suits installers and maintenance teams fitting or replacing check valves in water or compatible fluid lines. The brass body provides corrosion resistance for standard service conditions. This new valve arrives ready for installation in the specified line size.

Threaded Connection and Pressure Limits

The valve uses a threaded end connection for direct assembly into matching pipework without flanges or solder joints. Brass construction limits the maximum working pressure and temperature compared with steel or iron alternatives, so the installer must verify that system conditions stay within the valve’s rated range. The swing-disc design requires sufficient flow velocity to open fully and horizontal or vertical-up orientation to close reliably by gravity. California Proposition 65 warnings apply to chemicals present in the brass alloy.

3-Inch Nominal Size Decides Fit

The single specification that determines whether this is the correct part is the 3-inch nominal pipe size, which must match the piping schedule and diameter of the existing line. An undersized or oversized valve will not seal or thread properly, causing leaks or flow restriction. No other dimension or rating can compensate for a size mismatch, so confirm the line size before ordering.
