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

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.

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.

'
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.

This valve is made in M. H, 1 and 1^-in. sizes. The H-in. size is made in four types: angle, straightway, right-hand corner and left-hand corner patterns. The 54, I and IJ^-in. sizes are made in the angle and straightway patterns. The Xt-\n. size unless otherwise specified is made with %-in. outlets, thus avoiding the use of all K-in. pipe and reducing fittings.

Barnes & Jones Condensators
For returning the water of condensation to the
boiler from open return line systems independently of boiler pressure, without any change in operating conditions, and without air binding, or admitting steam to the return side of the system.
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.
