FTN Series Float & Thermostatic Steam Traps

Pressures to 125 PSIG (8.6 barg) temperatures to 450° F (232° C). 

Universal Four-Port Design

Four possible hookup combinations of the “H” pattern body and piping dimensions similar to other major manufactures allow maximum installation flexibility for easy replacement of other traps.  Inlet and outlet taps on larger sized traps located in the cover to permit larger capacities.

All Stainless Steel Internal Components

Hardened valves and seats.  Extra long life and dependable service.  Resists water hammer.  Protects against erosion and corrosion.

Balanced Pressure Thermostatic Element

Allows venting of non-condensable while operating at design pressure.

Rugged Welded Stainless Steel Element

Increases service life.

Wide Selection of Differential Pressures

Sizes ¾″ to 2″ available with 15, 30, 75 and 125 PSIG differential pressures.

Air Line Water Removal

Special configuration FTNA optimized for compressed air service.

Repairable In-Line

Can be serviced without disturbing system piping.

East to Maintain

Working parts lift out with top for quick inspection and maintenance.

Resists Corrosion

Stainless steel bucket provides maximum service life with minimum deterioration.

Minimizes Effects of Water Hammer

Open bucket design avoids collapse typical of sealed floats.

Suitable for Wide Variety of Loads / Applications

Horizontal and vertical models in thirteen body sizes are one of the most comprehensive inverted bucket trap lines available.

Withstands Severe Conditions

Heavy wall cast iron cover and body provide many years of trouble free service.

Smooth Action and Tight Shutoff

Stainless steel linkage, valve and seats are precision manufactured to insure optimal performance.

Ideal for “Dirty” Systems

Valve and seat located at top of trap and stainless steel strainers available on most horizontal models ensure long service.

Maximum Compatibility with Existing Installations

Pressure change assemblies are interchangeable with Armstrong, which guarantees maximum flexibility when stocking repair parts.
