Y-Type Cast Iron Strainers
250 lb Screwed 1/2"-3" Class 125 Flanged 2"-6" Class 250 Flanged 2"-6"
Screen chambers won't leak or crush
Both ends of the chambers are precisely machined. This means perfectly round and smooth seating surfaces, as well as a fixed chamber length. Since the screen seats snugly on the machined surface, no particle bigger than the screen opening can escape around the end of the screen.
Screwed retainers easy in, easy out
Straight threads mean it takes less torque to achieve a tight seal with proper gasket compression. Less torque is also required to remove the retainer. For you, that means less danger of "freezing in" than with hard-to-break tapered pipe threads.
Off-center blowdown connections for better dirt removal
Off-center drains on 2-1/2" and 3" strainers allow you to remove liquid and dirt nearly completely when blowing down the strainer. Also, less liquid will spill when the screen retainer is removed.
Many screen choices
Many screen materials, meshes and perforations are available.

- Float and Thermostatic (F&T) Steam TrapsThe More Your Steam Pressure Varies, The More You Need Armstrong F&T TrapsWhen steam pressure may vary from maximum steam supply pressure to vacuum, Armstrong F&Ts are your most energy-efficient choice. Our line of F&Ts brings Armstrong performance, dependability and long life to trapping services requiring continuous drainage with high air venting capacity. Thanks to separate orifices for condensate and air, they provide continuous condensate drainage and air venting-even under conditions of zero pressure. All the benefits detailed here have been designed into Armstrong F&Ts through long experience in the manufacture of pressure float-type traps. They assure you of optimum operating efficiency for long periods with minimum trouble. How they work Float and thermostatic traps are mechanical units that operate on both density and temperature principles. The float valve operates on the density principle. A level connects the ball float to the valve and seat. Once condensate reaches a certain level in the trap, the float rises, opening the orifice and draining condensate. A water seal formed by the condensate prevents live steam loss. Since the discharge valve is under water, it is not capable of venting air and non-condensables. When the accumulation of air and con-condensable gases causes a significant temperature drop, a thermostatic air vent in the top of the trap discharges them. The thermostatic vent opens at a temperature a few degrees below saturation, so it's able to handle a large volume of air-through an entirely separate orifice-but at a slightly reduced temperature. Built as tough as the jobs they do Armstrong float and thermostatic traps are unique in their super heavy duty construction. Armstrong uses high quality ASTM A48 Class 30 cast iron or ASTM A216 WCB cast steel-normally found in pressure vessels rated to 250 psi (17 bar) or 465 psi (32 bar). Internal mechanisms are made from stainless steel and are heavily reinforced. No brass cotter pins here. Valves and seats are stainless steel, hardened, ground and lapped to withstand the erosive forces of flashing condensate. Why go to all this trouble for traps normally recommended for low-pressure, modulating service? The operative word here is modulating. Modulating pressures mean widely varying loads, thermal cycling and high air and non-condensable gas loads. In other words tough service. Inferior, lightweight construction in this kind of service is a mistake waiting to happen. Trap failures on modulating pressure may lead to water hammer, corrosion and even damage to heat exchangers. Armstrong's published capacities are based on actual measurements of traps handling hot, flashing condensate. Competitive F&Ts may utilize theoretical calculated capacities. Armstrong uses its own steam lab to give you actual capacity-especially important on high-capacity traps such as those in our ultra-capacity line. Not only does Armstrong offer super heavy duty construction for long life and reliability, but we also supply the data to back up performance. Here's a simple, easy-to-remember summary The more your pressure varies, the more you need Armstrong F&Ts.

- The most reliable steam trap known&mdashthe inverted bucket&mdashprovides efficientcondensate drainage of virtually all types of steam-using equipment. Putthe inverted bucket to work in a tough cast iron package, and you have thebest of both worlds. Because they operate efficiently for longer periods oftime, Armstrong cast iron inverted buckets add solid energy savings to lowerreplacement/labor costs. All Armstrong cast iron inverted bucket steam trapsare repairable for even bigger maintenance savings.
A unique leverage system multiplies the force provided by the bucket to openthe valve against system pressure. The mechanism is free-floating, and hasno fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can collecton the orifice. Small particles of dirt are held in suspension until dischargedby the full differential purging action when the bucket sinks, pulling the valveoff the seat.
The discharge orifice is surrounded by a water seal, preventing live steamloss. Automatic air venting is provided by a small vent hole in the bucket, whichprovides 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.

Capacities to 2,850 lb/hr (1 295 kg/hr)
Armstrong CD-40 and CD-60 Series controlled disc traps contain a replaceable capsule, making it possible to renew a worn trap by simply replacing the capsule. A heating chamber in the shell ensures consistent operation. This steam jacket provides a relatively constant temperature in the control chamber regardless of ambient conditions. Cycling rate is controlled and does not increase when the trap is exposed to cold winds, rain or snow. CD-40 Series traps are also available with optional integral .045 perforated stainless steel strainer screens. CD-60 Series traps contain integral strainers with ratios of open area to inside area of pipe that equal or exceed those of most separate Y-type strainers.

- Thermostatic Wafer Steam TrapsArmstrong 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. It can also be used with the TVS 4000.
Armstrongs WT-3 is a carbon steel thermostatic wafer trap for superheated drip service. It features an exclusive non-welded wafer design, which eliminates problems associated with weld stress. The WT-3 has no thin-walled enclosures such as bellows or welded diaphragms. It is also resistant to water hammer. Choose NPT or BSPT screwed or socketweld connections.
The Series MT from Armstrong is sized precisely to accommodate the extremely low condensate loads found in most instrument steam tracer lines.
NOTE Since the normal operation of all suppressed temperature-discharge (subcooling) steam traps is to back up condensate, they should not be used on drip legs for saturated steam service, heating or process equipment. Exercise care in the maintenance of any thermostatic wafer trap with a small discharge area susceptible to clogging.
