Steam Filters

Armstrong’s stainless steam filters are designed for filtering steam to yield low differential pressure at high flow rates and are suitable for process steam and culinary steam. Steam filter elements are commonly regenerated to reduce pressure drop, remove settled contaminants, and prevent permanent contamination buildup. Armstrong provides steam filtration for a wide range of applications, including: aseptic packaging, breweries, chemicals, dairies, electronics, food and beverage, pharmaceuticals, and plastics. From industrial steam  to clean steam in sanitary applications, Armstrong can provide the filtration your company and industry requires.

Condensate Recovery

Armstrong’s condensate recovery solutions allow you to use all of the valuable Btu within your steam system. Depending on pressure, condensate leaving a trap contains approximately 20% of the heat energy transferred at the boiler in the form of sensible heat. Our condensate recovery systems are designed to provide efficiency and savings by helping you reduce costs for fuel/energy consumption, boiler water make-up and sewage treatment, and boiler water chemical treatment.

Pressure and Temperature Controls (Regulators and Control Valves)

Armstrong helps you manage your steam, air and liquid systems safely and efficiently with a full line of pressure and temperature controls, as well as condensate coolers and drain separators. By maintaining constant pressure or temperature for process control, our hardworking solutions help ensure uninterrupted productivity, day after day.

Pressure and Temperature Control Products


Armstrong offers strainers in wide range of sizes and materials to meet most pipeline straining requirements—all made to Armstrong’s high standards and guaranteed to be free from defects in workmanship or material. Armstrong Y-type strainers are available in cast iron, carbon steel, chrome-moly, forged steel, stainless steel and bronze. Connections come in screwed, socketweld and flanged configurations. Armstrong T-type strainers are available in stainless steel.

Air/Gas Vents

Armstrong’s float-type air/gas vents adjust instantly to variations in gas flow and pressure. Our air/gas vents handle gas removal from liquids with specific gravities as low as 0.40 and pressure to 2,700 psi (186 bar). Operation is completely automatic, and the simple design and quality mechanism make operation trouble-free and maintenance infrequent. Applications include hydronic heating systems, water service lines, water storage tanks, centrifugal pumps, gas lines, solvent filters and similar equipment. Available in a wide variety of sizes, end connections and construction materials.

Armstrong offers thermostatic air vents for positive venting of air and other non-condensable gases in equipment where air can accumulate in remote sections of chamber-type heat-transfer products such as jacketed kettles, retorts, vulcanizers and jacketed sterilizers.

Air Vents

Liquid Drainers

Armstrong’s hardworking liquid drainers are engineered to remove liquid continuously, automatically and dependably, even in the presence of dirt, grit or oil—without wasting air or gas. Our liquid drainers offer a long, trouble-free operating life, ease of repair, and minimal need for adjustment or maintenance. Liquid drainers may also be known as:  condensate drainers, compressed air drains, air traps, compressed air traps, float traps, water traps, or dump valves.

The burnished piston and metal reinforced graphite rings provide leak-proof shutoff while allowing an extended operating life, even at higher temperatures. All sealing valve components may be easily replaced in-line.

Our piston valves offer long-term, fire-proof operation, resistance to cavitation, and are designed to ensure actuation, even after many years without operation. Ideal for saturated and superheated steam, and hot water applications, and available in socket weld, BSPT, and NPT end connections. Flanged ends can be supplied upon request. Sizes from 15mm/1/2” NB to 40mm/1-1/2” NB and compatible with API, ASME, IBR, and DIN standards.

Unfired Steam Generators

Armstrong Unfired Steam Generators (USGs) are designed to produce pressurized clean steam using boiler steam or high-temperature hot water as an energy source. Typical uses for this clean steam include humidification, sterilization, pharmaceutical applications and food processing. Our USGs are designed to provide the correct balance of steaming area, coil size and control components to meet the specified requirements. In the event of a power failure, the over-pressure safety system shuts the unit down by closing both the feed-water and source steam valves.

Armstrong USGs are constructed and stamped in accordance with ASME code. All tanks are registered with the national Board of Boiler and Pressure Vessel Inspectors, and an insurance compliance certificate is furnished. Unfired steam generators that generate 50 psi (3.4 bar) or greater steam pressure will be 100% X-rayed in accordance with the ASME code.
