Find My Check Valve
The FBC™ is a compact, lightweight, insert wafer check valve that easily installs between two flanges. The in-line, spring assisted design prevents "water hammer" and "reverse flow". The FBC™ contains all of the proven features of the Basic-Check® valve developed by DFT® over 60 years ago. Like the Basic-Check®, the metal-to-metal sealing area of the disc and seat is precision lapped providing tight shut-off for applications involving liquids, gases or steam. Resilient soft seats are available for applications requiring bubble-tight shut-off.
