Legend Valve 105-405 Bronze Check Valve 1 Inch Soldered

Product Description

The LEGEND VALVE 105-405 is a bronze Y-pattern check valve designed for 1-inch soldered connections in plumbing and hydronic piping systems. It allows fluid flow in one direction and automatically prevents backflow without requiring manual operation. The Y-pattern body design provides lower flow resistance compared to swing or lift configurations, making it well-suited for systems where pressure drop is a concern. Rated at 300 WOG (Water, Oil, Gas), this valve handles demanding service conditions across a range of media. It is installed by licensed plumbers and pipefitters in both residential and light commercial applications.

This check valve is appropriate for use in domestic water supply lines, hydronic heating circuits, and other closed-loop piping systems where backflow prevention is required at a 1-inch connection point. The soldered end connections suit copper pipe installations that follow standard sweat-joint assembly practices. Its compact bronze body fits into tight mechanical spaces common in residential plumbing rough-ins and boiler rooms.

Key Features

• Y-pattern body reduces pressure drop compared to standard inline check valve designs
• 300 WOG pressure rating suitable for water, oil, and gas service
• Bronze body construction provides corrosion resistance in wet plumbing environments
• Soldered x soldered end connections for use with standard copper pipe
• 1-inch pipe size fits common residential and light commercial supply and distribution lines

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1-inch copper pipe systems using sweat-joint connections in plumbing, hydronic, and low-pressure gas piping applications rated to 300 WOG.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before cutting into the line. The valve body is typically marked with a flow-direction arrow and must be oriented correctly in the pipe run. Use standard soldering flux and lead-free solder for potable water applications, and allow joints to cool fully before restoring system pressure.
