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&ampT) Steam TrapsThe More Your Steam Pressure Varies, The More You Need Armstrong F&ampT TrapsWhen steam pressure may vary from maximum steam supply pressure to vacuum, Armstrong F&ampTs are your most energy-efficient choice. Our line of F&ampTs 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&ampTs 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&ampTs 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&ampTs.
