PRODUCTS--Steam Traps, Strainers, Air Traps, Steam and Oil Separators, Compressed Air Purifiers, Exhaust Heads, Boiler Feeders and Controllers, Alarm Water Columns, Water Gauges, Trycocks. "Airxpel" Bucket Type Steam Traps Are "double duty" traps, because they automatically discharge both air and condensate. Union connections make them easy to connect up. Also, furnished with screw con nections when desired. They save money for fittings and instal lation labor, by having straight through horizon tal pipe connec tions. The Cub sizes are made in H in., % in.. 1 in. Especially suitable for in dividual unit drainage cm heating and process equip-' merit. Also three "Master" sizes % in. to 2 in., for general service. "Emergency" Float Type Steam Trap Three valve trap with large capacity at high pressures. An ex ceptionally reliable trap for use in inac cessible places. Air Relief Traps For relieving air from forced circulation hot water heating systems, water supply lines, closed tanks, receivers, pumps, etc. "Tuway" Strainer May be used two ways-- k as a straight-way or angle 5 strainer, in either hori-1 zontal or vertical pipe line, because it has the . choice of two inlets at right angles to one another. For cleaning, flush through blow-off connection, or remove screen by unscrewing bottom plug. Separators--Steam and Oil Type " A" Vertical Type "S" Steam Horizontal Oil "Combination" Steam Traps Float Type with internal thermo static air bypass and strainer for pressures 0 to 40 lb. A modernly designed and very successful trap for vacuum and pres sure heating. "Victor" Low Pressure Steam Traps A heavy duty trap for large volumes of con densation at low pressures. We make separators of every type and all sizes for all pressures. Exhaust Heads Designed to eliminate noise and spray. T^ree types to select fromrrithe "Cyclone" Heavy Duty, and Standard Galvanized Steel--also, the cast iron type, to remedy all condi tions. Sizes 1 in. to 48 in.

This trap is made of bar stock throughout, no castings used. Body and bonnet of cold rolled steel, cadmium plated; cap of tobin bronze, valve and seat of heat treated stainless steel. For pressures 400 to 600 lb, bonnet and cap are stain less steel. Operation--Movement of the valve is governed by changes in pressure in control chamber (K). When handling ordinary condensate, tiny control flow bypassing through orifico>in center of valve reduces chamber pressure below inlet pressure and valve opens, allowing free discharge through seat. As condensate approaches steam temperature, low chamber pressure causes flashing, flow through center orifice is choked and pressure builds up in control chamber closing valve (F). Factory set to operate at all pressures up to 400 lb (or 600 lb) without change of valve seat. Advantages Light Weight--Yarway traps need no support--XA in. trap weighs only 1% lb. 2 in. trap weighs 8% lb. Small Size--They practically eliminate radiation losses--can be installed in cramped quarters--3^ in. trap measures 2yi in. long--2 in. trap, 4% in. long. Will not air bind. Require no priming. Insure quick healing. Operate on exclusive Impulse principle (U. S. Patents No. 2,051,732 dnd2,127,649.) Low Price--Often cheaper than re pairing old traps.
