The Answer to Failing Double Door Check Valves

Product Announcement from DFT Inc.


The Answer to Failing Double Door Check Valves-Image

The ALC® easily replaces unreliable double door / butterfly check valves.

-- No more door springs or hinge pin failures

-- No more leakage due to misalignment of the doors and seat

-- No more internal parts going down stream

-- No more reverse flow

The DFT ALC® is an in-line, spring-assisted, center guided "wafer" check valve designed to prevent "water hammer" and "reverse" flow.

The lightweight compact design fits between mating flanges and meets API 594 Face-to-Face dimensions. The ALC® is an easy to maintain check valve for applications involving liquids, gases or steam. Tapped holes are provided in the body for lifting lugs to assist with installation.
