    Continuous flow or on-off float drain traps

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

    No. 21—A small, high-quality, economical drain trap for use on drainage jobs where dirt and oil are not encountered. It employs a single lever with a fixed pivot.

    No. 21-312—Forged steel version of the No. 21, with larger float and higher leverage.

    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.
