Nibco nf7q00d Copper Press 2 Inch Lift Check Valve 200 Cwp

Product Description

The NIBCO nf7q00d is a 2-inch copper press ring inline lift check valve rated at 200 CWP (cold working pressure). It is designed to allow flow in one direction and automatically prevent backflow when pressure drops or reverses. The valve uses a press-ring connection style, eliminating the need for soldering or threading during installation. It is built for inline installation in pressurized plumbing and hydronic systems. Licensed plumbers and pipefitters install this type of valve in residential and light commercial water distribution, heating, and cooling piping systems.

This valve is suited for inline applications in copper press piping systems operating at or below 200 CWP. The press-ring end connections make it compatible with standard copper press fitting systems, allowing faster assembly compared to sweat or threaded alternatives. Typical installations include domestic water supply lines, hydronic heating loops, and chilled water systems where backflow prevention is required without a serviceable check mechanism in the line.

Key Features

• Copper construction for corrosion resistance in water and hydronic service
• Press-ring end connections for tool-pressed, no-solder installation
• Inline lift check design provides automatic backflow prevention
• Rated at 200 CWP for pressurized plumbing applications
• 2-inch nominal size suits main distribution and branch piping runs

Compatibility

Designed as an OEM-style replacement or new-installation component for 2-inch copper press piping systems requiring inline backflow prevention.

Installation Notes

Installation of this valve should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Depressurize and drain the system before cutting into existing piping. Press-ring connections require a compatible press tool and approved jaw or ring set sized for 2-inch copper fittings. Verify flow direction markings on the valve body before pressing connections.
