SKU CH-ACCP-Y5AB5

  • In-line check design prevents backflow automatically
  • 1/2" CXC connection fits copper pipe directly
  • California Prop 65 warning disclosed for compliance
  • New condition ensures reliable performance from installation

1/2" No-Lead Bronze Check Valve

The Legend Valve 105-463NL is a 1/2-inch in-line check valve built from S-455 no-lead bronze. It suits plumbing and hydronic systems where lead-free components are required by code. Installers use it to prevent reverse flow in potable water lines and heating loops.

One-Way Flow Limitation

The valve permits flow in a single direction only and cannot be used where bidirectional control is needed. It offers no manual shut-off or flow-regulation function. Systems requiring positive isolation must add a separate ball or gate valve upstream or downstream.

No-Lead Bronze Body with CXC Ends

The no-lead bronze construction meets low-lead mandates and resists dezincification in aggressive water conditions. CXC copper sweat connections demand proper flux, solder and torch technique for leak-free joints. California Proposition 65 warnings apply to chemicals present in the material.

  • No-lead bronze construction protects drinking water
  • In-line check design prevents backflow automatically

Questions about this item

How do I know the 105-463NL is the right Legend Valve for my system?

The 105-463NL is a 1/2 inch S-455 no-lead bronze in-line check valve; match the size and the S-455 designation to your piping spec.

What does the S-455 rating tell me about flow performance once installed?

The S-455 marking identifies the valve series and no-lead bronze construction; it confirms material compliance rather than a flow-rate number.

What connection standard does the CXC end use and what pipe does it accept?

CXC indicates copper-by-copper sweat ends for 1/2 inch copper tube; solder the valve directly into a copper line.
