TT SERIES THERMOSTATIC STEAM TRAPS

ALL STAINLESS STEEL

For pressures to 300 psig (20 bar) . . .

Capacities to 3,450 lb/hr (1568 kg/hr)

The balanced-pressure bellows thermostatic steam trap has a sealed, stainless steel body that is lightweight, compact and highly resistant to corrosion. The cage, bellows, valve and seat are all assembled into a precisely calibrated operating unit that ensures positive opening and closing action at slightly below steam temperature.

The unique stainless steel construction is smaller and much lighter than comparable cast iron, brass or steel traps. TTF-1 is available with straight-thru or right-angle connections. TT-2000 with the 360˚ universal stainless steel connector comes with either a standard connector or the IS-2 connector with integral strainer and is adaptable to Armstrong’s Trap Valve Station (TVS).

THERMOSTATIC WAFER STEAM TRAP

STAINLESS STEEL OR CARBON STEEL

For pressures to 600 psig (41 bar) . . .

Cold water start-up capacities to 1,600 lb/hr (726 kg/hr)

 

Armstrong offers several thermostatic wafer steam traps. The WT-1 is ideal for low-capacity steam tracers and features an exclusive non-welded wafer design, a sealed stainless steel body and an internal strainer screen two to three times larger than that of other thermostatic traps. Choose from NPT or BSPT screwed connections.

 

The WT-2000 is adaptable to a 360° connector to expand piping options and simplify installation. Choose NPT or BSPT screwed or socketweld connections. The WT-2000 is also available for use on the IS-2 stainless steel connector with integral strainer and can be used with the Armstrong Trap Valve Station (TVS) 4000.

TVS 4000 SERIES STAINLESS STEEL TRAP VALVE STATION

The stainless steel version of the remarkable Armstrong Trap Valve Station (TVS) gives you two piston-style isolation valves, a test valve and an integral stainless steel strainer with blowdown valve—all merged together in a single, versatile package that takes up only 5 inches! What’s more, the unique Armstrong connector makes the TVS compatible with all of these:

 

  • Inverted bucket

  • Disc

  • Thermostatic

  • Thermostatic wafer

  • Bimetallic

  • Float and thermostatic

  • Two-bolt steam traps from other manufacturers

INVERTED BUCKET STEAM TRAPS
401-SH/501-SH Series
SKU: ARMIB401

Carbon steel or stainless steel for vertical installation

For pressures to 1,540 psig (105 bar)

Capacities to 1,300 lb/hr (590 kg/hr)

Armstrong’s 401-SH/501-SH Series inverted bucket superheat trap line is made for overcoming the difficult combination of superheat and high pressure/low load service. To survive this most severe steam service, Armstrong created an inverted bucket trap with a unique accumulation chamber. The chamber collects sufficient condensate to ensure full discharge cycles. A cup in the chamber floats up and down on the steam inlet tube, sealing it off as the condensate level rises. At the same time as the chamber collects condensate, steam continues to flow under the bucket, making sure that the discharge valve closes tightly until the condensate rises into the trap body and the bucket falls down.

The operation is on/off, no throttling or dribbling. In addition, you get all the familiar benefits of an inverted bucket steam trap.

 

  • Reliability. High resistance to wear, corrosion and water hammer with no gaskets.

  • Operation against back pressure. A unique leverage system multiplies the force provided by the bucket, to open the valve against system pressure.

  • Freedom from dirt problems. The mechanism is located at the top. No dirt can collect on the orifice. Small particles of dirt will be held in suspension until discharged by the full differential purging action.

  • Zero steam loss. The discharge orifice is surrounded by a water seal, which prevents live steam loss. Automatic air venting is provided by a small hole in the bucket.

  • Trouble-free operation. Inverted bucket traps require no adjustment. They do not allow condensate backup and are resistant to water hammer.

INVERTED BUCKET STEAM TRAPS
1000 Series
SKU: ARMIB1000

All stainless steel for vertical installation For pressures to 650 psig (45 bar)

Capacities to 4,400 lb/hr (2000 kg/hr)

Armstrong 1000 Series stainless steel inverted bucket steam traps normally last three to four times longer than conventional traps used in identical services. Heat-treated stainless steel valves and seats are of the same design, material and workmanship as those used in traps for pressures up to 900 psig/62 bar and temperatures up to 900˚F/482°C. More compact than cast iron or carbon steel equivalents, 1000 Series traps are ideal for trapping applications such as tracer lines, steam mains and heating/process applications. The 1000 Series are guaranteed for five years.

INVERTED BUCKET STEAM TRAPS
980 Series
SKU: ARMIB980

Cast steel for horizontal installation with integral strainer

For pressures to 600 psig (41 bar)

Capacities to 4,400 lb/hr (2000 kg/hr)

Armstrong offers two sizes of cast steel inverted bucket traps with in-line horizontal pipe connections and integral strainers with a choice of screwed, socketweld or flanged connections. A unique leverage system multiplies the force provided by the bucket to open the valve against system pressure. The mechanism is free-floating and has no fixed pivots to create wear or friction. Because the mechanism is located at the top of the trap, no dirt can collect on the orifice. Small particles of dirt are held in suspension until discharged by the full differential purging action when the bucket sinks, pulling the valve off the seat.

The discharge orifice is surrounded by a water seal, which prevents live steam loss. Automatic air venting is provided by a small vent hole in the bucket, which provides continuous automatic air and CO2 venting at steam temperature. Inverted bucket traps drain continuously, although discharging intermittently, allowing no condensate backup. They are also resistant to water hammer.

880 Series
SKU: ARMIB880

Cast iron for horizontal installation with integral strainer

For pressures to 250 psig (17 bar)

Capacities to 4,400 lb/hr (2000 kg/hr)

The most reliable steam trap known—the inverted bucket—provides efficient condensate drainage of virtually all types of steam-using equipment. Put the inverted bucket to work in a tough cast iron package, and you have the best of both worlds. Because they operate efficiently for longer periods of time, Armstrong cast iron inverted buckets add solid energy savings to lower replacement/labor costs.

Armstrong cast iron inverted bucket traps are repairable for even bigger maintenance savings. A unique leverage system multiplies the force provided by the bucket to open the valve against system pressure. The mechanism is free-floating and has no fixed pivots to create wear or friction.
