Product Identity

This Legend Valve 105-205 is a 1" S-451 brass swing check valve designed for plumbing installations that require one-way flow control. It suits installers and maintenance teams needing a reliable component for water or compatible fluid lines. The valve arrives new and ships directly from the manufacturer. Orders of $75 or more ship free.

Proposition 65 Notice

The product carries a California Proposition 65 warning because it contains a chemical known to the state to cause cancer. A second Proposition 65 warning indicates the same product contains a chemical known to cause birth defects or other reproductive harm. These notices inform safe handling and installation practices but do not describe a bundled accessory or software change.

Suitability Guidance

This valve suits projects that specify a 1" brass swing check valve with the S-451 designation. Buyers who need a different pipe size, a different body material, or a spring-loaded check mechanism should look at alternative models. The warnings also mean it is not the right choice for applications that prohibit the listed chemicals.

Questions about this item

Does the 1" S-451 brass swing check valve need periodic inspection or replacement of internal parts?

The brass body and swing-disc design have no user-serviceable components; routine inspection for debris or mineral build-up is the only maintenance normally required.

What limits continuous flow through the 1" S-451 check valve during all-day operation?

The 1-inch port size and swing-disc geometry set the maximum flow capacity; pressure drop across the valve becomes the practical limit under sustained use.

How much noise, heat or power does the 1" S-451 brass swing check valve produce when running all day?

The valve has no moving parts under power, so it generates no heat, draws no electricity and makes only the normal water-flow sound of a swing check.
