  • Bronze construction resists corrosion for long service life
  • Y-pattern design reduces flow restriction in plumbing systems
  • 1-1/4 inch connection fits standard piping configurations
  • Check valve prevents backflow to protect equipment
  • California Proposition 65 warning indicates regulated chemical content

1-1/4" Bronze Y-Pattern Check Valve

The Legend Valve 105-406 S-453 is a bronze Y-pattern check valve designed for plumbing systems requiring 1-1/4 inch connections. It allows flow in one direction while automatically preventing backflow to protect pumps and piping. This component suits residential and light commercial installations where reliable non-return performance is needed.

Pressure and temperature limits

The valve operates within the pressure and temperature boundaries defined by its S-453 bronze construction and Y-pattern body design. Installers must verify that the system's working pressure and fluid temperature stay within the valve's rated class to avoid leakage or premature wear. California Proposition 65 warnings indicate the presence of chemicals known to cause cancer and reproductive harm.

Replacing swing or lift check valves

This Y-pattern valve replaces older swing or lift check valves where a more compact body and smoother flow path are preferred. The upgrade is worthwhile when reducing turbulence and pressure drop across the valve improves system efficiency. It is not suited for applications requiring a larger bore size or a different end-connection standard.

Questions about this item

Which Legend Valve 105-406 check valve version should I choose for a 1-1/4 inch line?

This is the single 1-1/4 inch S-453 bronze Y-pattern check valve listed under model 105-406; no other sizes or models appear in the listing.

What does the S-453 bronze Y-pattern design mean once the valve is installed?

The Y-pattern body gives a straighter flow path than a swing check, reducing turbulence and pressure drop, while the bronze construction resists corrosion in water systems.

How does the 1-1/4 inch connection standard limit what piping I can use?

The valve has 1-1/4 inch threaded ends that mate with matching NPT pipe fittings; it cannot connect directly to copper sweat, press-fit or flanged pipe without adapters.
