1/2" No Lead Bronze Y-Pattern Check Valve

The Legend Valve 105-303NL is a 1/2-inch Y-pattern check valve constructed from no-lead bronze alloy. It is intended for plumbing installations where backflow prevention is required in potable water systems. The T-453 designation identifies the specific valve configuration. This component suits professional plumbers and maintenance crews working on residential or light commercial piping.

Sustained flow characteristics

The Y-pattern body provides a straighter flow path compared to swing-check designs, reducing turbulence during continuous operation. Bronze construction resists corrosion from treated water supplies over long service periods. The check mechanism opens under forward pressure and closes automatically when flow stops or reverses. No lead content ensures compliance with regulations for drinking water contact.

California Proposition 65 notice

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The warning applies to the valve as supplied and does not describe a performance limitation. Installers should follow standard safety practices when handling and joining bronze fittings. Buyers needing a valve without this warning must select a different material or manufacturer.

Questions about this item

How much heat does the 1/2" T-453 NL Y-Pattern Check Valve generate when running all day?

The valve has no moving electrical parts and creates no measurable heat during continuous operation; fluid temperature depends only on the system it serves.

What piping must I already have to install the 1/2" T-453 NL check valve?

You need 1/2 inch nominal pipe with compatible threads or solder connections matching the valve ends for a leak-free fit.

Will the No Lead bronze body of the 105-303NL valve corrode when paired with older copper or galvanised lines?

The no-lead bronze resists dezincification and is compatible with copper; use a dielectric union when joining to galvanised steel to prevent galvanic corrosion.
