Legend Valve 105-404 Check Valve 3/4 in Y-pattern Bronze

Product Description

The LEGEND VALVE 105-404 is a 3/4 inch Y-pattern check valve designed to prevent backflow in potable water, hydronic, and general plumbing systems. Constructed with a bronze body, this valve uses a soldered (sweat) end connection on both ends, making it a reliable choice for copper pipe installations. Rated at 300 WOG (Water, Oil, Gas), it is built to handle the pressure demands of residential and light commercial plumbing applications. Licensed plumbers and pipefitters install this valve to maintain unidirectional flow and protect equipment and piping from reverse pressure conditions.

The 105-404 is suited for residential and light commercial plumbing systems where copper pipe is the standard. The Y-pattern body design offers lower pressure drop compared to standard swing check configurations, which is beneficial in systems where flow efficiency matters. Typical install scenarios include domestic water supply lines, heating system supply and return piping, and water service entry points where backflow prevention is required.

Key Features

• Y-pattern body design provides lower pressure drop than inline swing check valves
• Bronze body construction offers corrosion resistance in water and hydronic service
• Soldered (sweat) x soldered end connections for use with standard copper pipe
• 300 WOG pressure rating supports residential and light commercial system pressures
• 3/4 inch pipe size fits common domestic water and hydronic supply lines

Compatibility

Designed as an OEM-style replacement or new-install check valve for 3/4 inch copper pipe systems in residential and light commercial plumbing and hydronic heating applications.

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 relieve system pressure before cutting into any existing line. Use proper soldering technique and lead-free solder where required by code for potable water systems. Observe the flow direction arrow on the valve body to ensure correct orientation before completing the solder joints.
