Legend Valve 105-207 Swing Check Valve 1-1/2 in Solder

Product Description

The LEGEND VALVE 105-207 is a swing check valve designed for 1-1/2 inch copper piping systems with soldered end connections on both sides. It allows fluid flow in one direction and closes automatically to prevent backflow when flow pressure drops. The brass body provides corrosion resistance suitable for potable water and hydronic heating applications. Rated at 200 WOG (Water, Oil, Gas), this valve handles typical residential and light commercial service pressures. Licensed plumbers and HVAC service technicians install this valve in supply lines, hydronic loops, and domestic water systems where backflow prevention is required without an external actuation source.

The 105-207 is well suited for residential and light commercial plumbing and hydronic heating systems. It installs inline on 1-1/2 inch copper pipe using standard sweat soldering. Typical applications include domestic hot and cold water supply lines, boiler system piping, and circulator pump discharge lines where passive backflow prevention is needed. The swing-type disc mechanism operates without springs or external controls, relying on gravity and flow reversal to seat and unseat.

Compatibility

Designed as an OEM-style replacement or new-installation swing check valve for 1-1/2 inch copper piping systems using soldered end connections in plumbing and hydronic heating applications.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off the water supply and fully drain the line before cutting in or replacing this valve. Use standard sweat soldering tools and lead-free solder compliant with local potable water regulations when installing on domestic water systems. Verify the flow direction arrow on the valve body is oriented correctly with the intended direction of flow before completing the solder joints.
