Legend Valve 105-466 1-1/4" S-455 CXC In-Line Check Valve

Application and Fit

This Legend Valve 105-466 is a 1-1/4" S-455 CXC in-line check valve designed for plumbing systems that require unidirectional flow control. It suits installers and maintenance teams working with copper piping who need a reliable bronze body with copper-to-copper connections. Buyers who need a different connection type, a larger diameter, or a valve rated for higher pressure service should look elsewhere.

Sustained Flow Behaviour

The bronze construction resists corrosion during continuous water service, maintaining sealing integrity over extended periods without the degradation seen in short-term test cycles. The in-line design keeps pressure drop consistent across long runs, avoiding the flow instability that can appear when valves are cycled rapidly. It does not incorporate a spring-assisted closure, so reverse-flow response depends entirely on system back-pressure.

Thermal, Noise and Power Profile

As a passive mechanical component, the valve draws no electrical power and generates no operational noise of its own. The bronze body transmits fluid temperature without adding heat, so surrounding insulation requirements match the pipe specification. California Proposition 65 notices indicate the presence of chemicals known to cause cancer and reproductive harm, requiring appropriate handling during installation.
