Think* to the proven dependability and completeness of the Clark steam trap and regulator lines, power engineers can meet most of their requirements limply by calling a Clark representative. For there's a "right" Clark steam trap for every purpose. Clark makes the famous patented Duo-Step inverted bucket traps that handle doubt* the usual amount of condensate. In addition, Clark manu factures open bucket and float type traps as well as pressure regulators and strainers. So call on dark for <11 fluid control requirements. There are Clark repre sentatives in most major cities. MIIIS "CIO" FIOAT Tiar. for drolnoa* whera continuous flew I* Oatlrad, or for male. Inlnlng liquid levels.
