Brass Swing Check Valve 1/2" T-451

The Legend Valve 105-103 is a 1/2 inch brass swing check valve designed for plumbing systems that require one-way flow control. It suits installers and maintenance teams working on water supply lines where backflow prevention is needed. The T-451 model provides a straightforward mechanical barrier without external power or complex controls. Its brass construction offers standard corrosion resistance for typical potable water applications.

California Proposition 65 Compliance

This product carries California Proposition 65 warnings for chemicals known to cause cancer and birth defects or other reproductive harm. The notices are regulatory labels required for sale in California and do not alter the valve's mechanical function or installation method. Buyers should retain the documentation for workplace safety records or building-code inspections where such disclosures are mandatory. No additional software, seals or specialised tools are bundled with the valve.

Installers Needing Simple Backflow Prevention

The valve fits projects that need a basic swing-check mechanism in a 1/2 inch line and where brass material is specified. It is not suited for systems requiring spring-loaded silent closure, vertical-flow orientation without gravity assist, or certified lead-free alloys beyond standard brass composition. Buyers who need larger diameters, flanged ends or automated actuation should look at other valve types.

Questions about this item

Does the brass swing-disc mechanism need any periodic lubrication or seal replacement?

The valve uses a simple brass swing-disc design with no serviceable seals or lubrication points, so no routine maintenance is required beyond checking for debris.

What flow restriction appears first when the valve runs continuously at full capacity?

The 1/2-inch port and swing-disc geometry set the flow limit; pressure drop across the disc becomes the governing restriction under sustained flow.

How much heat or vibration does the valve generate during all-day operation?

Being a passive brass check valve with no moving parts other than the disc, it produces no measurable heat, vibration or noise of its own.
