Flomatic 7937VFD Ductile Iron Check Valve 2 Inches 600 Psi

Product Description

The FLOMATIC 7937VFD is a 2-inch ductile iron check valve engineered for demanding water and fluid control applications. The body, poppet, and guide are manufactured from high-strength ductile iron with a patented design and finished with an epoxy coating for corrosion resistance. Connections are threaded female NPT. The valve seals with a Nitrile (Buna-N) elastomer and is rated for pressures up to 600 psi and temperatures up to 180 degrees F. Licensed plumbers and pipefitters install this valve in commercial and industrial piping systems where backflow prevention is required.

The 7937VFD is suited for both vertical and horizontal installation orientations, giving installers flexibility in tight mechanical spaces or complex piping layouts. Typical applications include water supply lines, pump discharge piping, and fluid handling systems in commercial buildings, municipal infrastructure, and industrial facilities. The epoxy-coated ductile iron construction holds up in environments where corrosion or high operating pressures are a concern.

Key Features

• High-strength ductile iron body, poppet, and guide with patented design
• High-build epoxy coating for corrosion resistance
• Nitrile (Buna-N) seal for reliable shutoff across common fluid media
• Threaded female NPT connections for standard pipe installation
• Rated to 600 psi maximum operating pressure
• Suitable for vertical or horizontal installation

Compatibility

Designed as an OEM-style replacement or new-install check valve for 2-inch threaded NPT piping systems in commercial and industrial plumbing and fluid-handling applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the system fully before removing or installing any valve. Confirm flow direction arrow on the valve body is aligned with intended flow direction before threading connections. Use appropriate pipe sealant or PTFE tape on NPT threads — do not overtighten, as ductile iron fittings can crack under excessive torque.
