Float Type Steam Traps

The Armstrong Float Type Steam Trap is designed to provide efficient condensate removal and optimal performance in steam systems. Known for its robust construction and reliable operation, it is ideal for a wide range of industrial applications.

Key Features

  1. Durable Construction:

    • Made from high-quality materials such as ASTM A48 Class 30 cast iron and ASTM A216 WCB carbon steel, Armstrong steam traps are built to withstand high pressures and temperatures, ensuring longevity and consistent performance.

  2. High Capacity and Pressure Handling:

    • The A & AI Series models can handle capacities up to 8,600 lb/hr (3,900 kg/hr) with a maximum allowable pressure of 175 psig (12 bar) and a maximum temperature of 377°F (191°C) (Armstrong | Americas).

    • The LS & MS Series models offer higher capacities, up to 280,000 lb/hr (127,000 kg/hr), with maximum allowable pressures of 450 psig (31 bar) and temperatures up to 650°F (343°C) (Armstrong | Americas).

  3. Advanced Design:

    • Featuring a balanced pressure phosphor-bronze bellows encased in stainless steel, these steam traps ensure effective air venting and condensate drainage, even under varying load and pressure conditions.

    • The FT-2000 and FT-2022 models incorporate a sealed stainless steel body and are compatible with the Armstrong 360° Universal Connector or Trap Valve Station, facilitating in-line trap replacement without disturbing the piping system (Armstrong | Americas).

  4. Versatile Installation:

    • The FT-4000 Series is designed for flexible installation options in any piping configuration, making it suitable for diverse industrial setups. With a maximum allowable pressure of 485 psig (33 bar) and temperature of 600°F (315°C), these models are highly resistant to corrosion and tampering (Armstrong | Americas).


Armstrong Float Type Steam Traps are ideal for heating, process, and other industrial systems where reliable condensate removal and energy efficiency are crucial. Their robust design and advanced features help enhance system performance, reduce maintenance costs, and ensure safe operation.
