Detroit Boiler Draw Off Cocks A more pleasing line of Packless Radiator Valves for steam, hot water, vapor and vacuum heating systems. The Detroit Packless Radiator Valves, Bellows Type, have no rotating or slid ing parts exposed to the steam or water. The operating parts are completely en closed in a strong, elastic brass bellows which expands and contracts as the valve is opened and closed. Steam, . water or air cannot pass through this metal barrier and leak through the stem opening. Conversely, no air can get into the system through the Radiator Valve, which is so necessary for a per fect and economical working vacuum system. The metal Bellows is of an improved type and will last as long as the heating plant itself. A new and better design of handle is offered for the first time. It is a hard rubber finished, molded type which will not break or lose its finish and which is non-conductive of heat. It will not work loose on the stem. The workmanship and finish of The Detroit Packless Radiator Valves, Bel lows Type, are of the highest grade. They are of compact and pleasing ap pearance, and due to the absence of complicated and friction-producing mech anism, turn very easily when being opened or closed. Manufactured in angles, right and left hand corners and globes, one half to. two inch sires. In satin finish with polished trim This improved cock has an outlet which is slightly inclined, to facilitate attachment of a hose, if desired. It has a stuffing box which prevents any leakage and consequent flooding of floor when unscrewed. The seat is a metal to metal and has been heavily reinforced, so that it cannot be distorted should excessive pressure be used when the cock is installed.
