Legend Valve 105-004NL 3/4 in Press Swing Check Valve

Product Description

The LEGEND VALVE 105-004NL is a 3/4-inch swing check valve designed for press-end installation in commercial and residential plumbing systems. The valve uses an EPDM rubber elastomer disc to provide reliable one-directional flow control, preventing backflow without requiring manual operation. The body is cast brass, which offers corrosion resistance and durability in potable water and hydronic applications. This valve is suited for licensed plumbers and pipefitters working on press-fit piping systems where lead-free compliant components are required.

The 105-004NL is intended for use in press-end piping systems, making it a fit for new construction and retrofit projects where soldering is not preferred or permitted. Its swing-style check mechanism is well suited to horizontal or vertical installations in residential water distribution and light commercial hydronic lines. The lead-free cast brass construction meets requirements for use in potable water systems.
