Continuous flow or on-off float drain traps

Armstrong’s line of snap action drain traps includes two basic models available in cast iron and forged steel. The floats are light enough to handle light liquids.

No. 71-A—Wide-open, tight-shut drain trap for use where fine dirt and grit may be present or where liquid load is light. A flat spring in the leverage system holds the valve closed until the trap body is nearly full of water. Then it snaps open, washing dirt through. When the trap body is nearly empty, the spring snaps the valve shut.

No. 71-315—Forged steel version of No. 71-A.

CAUTION: Ball float drain traps are not recommended where heavy oil, sludge or considerable dirt are encountered in lines. Under these circumstances, use Armstrong inverted bucket BVSW traps.
