The MATCO-NORCA 525t05lf is a lead free, spring loaded, inline check valve constructed from bronze. It is designed to allow fluid flow in one direction only, preventing backflow in potable water and plumbing distribution systems. The spring loaded mechanism provides reliable closure without relying solely on gravity or line pressure, making it suitable for horizontal, vertical, and angled installations. Licensed plumbers and pipefitters install this valve in residential and light commercial water supply lines where backflow prevention and lead free compliance are required.
This valve is sized for 1 inch pipe and is intended for inline installation within water supply, hydronic, or plumbing distribution piping. Its bronze construction resists corrosion in wet service environments. The lead free designation meets regulatory requirements for use in potable water systems, including applications subject to state and local plumbing codes that mandate lead free materials in drinking water contact services.
Designed as an OEM-style replacement or direct installation check valve for 1 inch inline plumbing applications requiring lead free bronze construction.
Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code or local equivalent. Shut off the water supply and relieve system pressure before removing any existing valve or fitting. Ensure pipe threads or connections are clean and properly sealed with an approved thread sealant rated for potable water service. Verify flow direction markings on the valve body before final installation.
