The DFT®  model 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 downstream

-- 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. Watch our Video.

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.
