Economical, compact, insert wafer check valve

Product Announcement from DFT Inc.

The FBC® is an economical, 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 70 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.
