Specialties, Heating Armstrong Machine Works 352 Maple Street Three Rivers, Mich. District Sales Offices in 36 Cities Exclusive Manufacturers of Armstrong Steam Traps Armstrong Steam Traps Armstrong steam traps are made in types and sizes to meet all condensate draining requirements. They are available for pressures up to 600 lb. pulsating pressures, high temperatures, acid con ditions and for special services of all kinds. They are ideally suited for draining unit heaters, and steam heating systems. Armstrong traps have many note worthy advantages. They automatically discharge entrapped air with the con densate. They can not become air bound. They are positive in operation--the valve is either wide open or tightly closed--wire A No. SO Armstrong Trap under Unit Heater drawing and subsequent erosion of valves and seats are eliminated. Being water sealed at all times, no live steam can escape. The unique construction gives a large capacity for a small size. Because of their small size, their cost is low and installation is a simple matter. No special fittings or supports are necessary. The sturdy construction and special wear- resisting parts insure long life and a minimum of maintenance. , No. Si The Nos. 30 and 31 traps are especially adapted for low or high pressure radiation up to 125 and 150 lb. respectively. Their low cost permits free use. A trap on each unit insures perfect drainage. A thermic unit is incorporated in each trap which holds the valve open until the trap becomes hot. This assures rapid heating of equipment. The Nos. 2, 3 and 4 Armstrong Traps are the standard type for general service up to 300 lb. pressure. The Nos. 30S to 4S Armstrong Traps are for service where there are pulsating pressures due to reciprocating engines and pumps drawing steam from a line. For pressures up to 600 lb., steel bodies are used. The standard Armstrong Traps with steel bodies are designated as Nos. 42, 43 and 44. The special traps are numbered 42S, 43S and 44S. Traps for higher pressures can be furnished on special order. In Regard to Capacities smaller valves and orifices, traps for high pressures have less capacity than the same trap for lower pressures. Always state maximum pres sure when ordering steam traps. SIZES AND CAPACITIES OF ARMSTRONG STEAM TRAPS Pipe Size. Ctpifitif* at 30-lb. Pres*. No. Diam. Height In. In. Weight Lb.

' The Barnes & Jones organization offers an advisory and consulting service believing that the manufacturer of a heating system often --" is in the best position to give practical assistance in the solution of heating problems. On request, members of our staff will consult with and advise engineers, contractors or users as to the most advantageous manner in which Barnes & Jones apparatus can be installed and operated or adapted to special installations. When __ . desired, our Service Department will furnish installation details and work with engineers, contractors or users to gain the best results in installation or operation. Factory Tested Each and every appliance used in the Barnes & Jones Modulation Vapor and Vacuum Heating Systems is tested, inspected and adjusted at our own factory before shipment, to meet all the con ditions which 30 years' experience in the develop ment of heating apparatus have shown us are likely to arise.

Barnes & Jones Blast Traps Combination float and thermostatic traps with an air and water capacity large enough to take care of the condensation from the largest vento stacks, dry kiln coils, hot water heaters and other units con densing large quantities of steam at low pressures. Barnes & Jones Vent Traps The air from a Barnes & Jones Vapor System is discharged to the atmosphere through a Barnes & Jones Vent Trap. This vent trap is equipped with a float valve to prevent the discharge of water and also with a ball check valve which allows the free discharge of air but pre vents its return into the system, thus enabling Barnes & Jones Vapor Sys tems to operate in many cases under vacuum conditions, with a resultant saving in fuel.
