Legend Valve 105-406 Y-pattern Check Valve 1-1/4 in

Product Description

The LEGEND VALVE 105-406 is a Y-pattern swing check valve designed to prevent backflow in copper piping systems. Built with a bronze body, this valve connects via sweat (soldered) ends on both sides and carries a 300 WOG (Water, Oil, Gas) pressure rating. The Y-pattern body geometry reduces flow turbulence and pressure drop compared to standard inline check valve designs. It is sized for 1-1/4 inch pipe and is suited for installation by licensed plumbers in commercial and residential hydronic, domestic water, and mechanical piping systems.

This check valve is used in applications where one-directional flow must be maintained and backflow prevention is required. Common install scenarios include domestic cold and hot water supply lines, heating and cooling distribution loops, and general mechanical piping where 300 WOG service conditions apply. The soldered end connections make it appropriate for copper tube systems following standard sweat-fitting practices.

Key Features

• Y-pattern body design reduces pressure drop and turbulence through the valve
• Bronze body construction provides corrosion resistance in water and hydronic service
• Soldered (sweat) connections on both ends for copper tube installation
• 300 WOG pressure rating suitable for water, oil, and gas service
• 1-1/4 inch pipe size for mid-range residential and light commercial applications

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1-1/4 inch copper tube systems rated to 300 WOG service conditions.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line completely before soldering. Use standard sweat-fitting techniques with appropriate flux and solder rated for potable water service where applicable. Observe the flow-direction arrow marked on the valve body to ensure correct orientation in the line.
