These Steam traps are used where frequent System wash down is required or when rust and other surface corrosion cannot be tolerated such as in facilities used for Food and Beverage or Pharmaceutical production.\u003c\/p\u003e\u003cp\u003eDRIP, PROCESS: FTTS Series steam traps with CF8M Stainless Steel Body and in-line pipe connections are used for the removal of condensate and air in HVAC and industrial process applications such as unit heaters, water heaters, pressing machines, heat exchangers and coils. They works same as FTT Series, however the FTT Series have Max Operating Steam Pressure up to 300 PSIG but FTTS Series have it up to 225 PSIG.\u003c\/p\u003e\u003ch2\u003eHow It Works\u003c\/h2\u003e\u003cp\u003eFloat and thermostatic traps contain a float and seat mechanism with a separate thermostatic element which work together to remove both condensate and air from the steam system. The float, which is attached to a valve, rises and opens the valve when condensate enters the trap. This allows the condensate to discharge. Air is discharged through the thermostatic air vent to the outlet side of the trap. Steam entering the trap causes the thermostatic element to expand, closing the air vent and trapping the steam.\u003c\/p\u003e\u003ch2\u003eSelection \/ Sizing \/ Capacities\u003c\/h2\u003e\u003cp\u003eThe PMO (maximum operating pressure) rating of model selected must meet or exceed the maximum steam pressure or the trap may not open. For example; the FTTS-145 has a PMO of 145 psi. Condensate capacity (lbs\/hr) of the trap is based on the differential pressure across the trap. For drip applications, a 1\/2\" FTTS size is generally sufficient to exceed warm-up loads with a 2X safety factor. The condensate loads (lbs\/hr) for process applications are normally calculated at the maximum steam pressure; then an appropriate safety margin is applied in order to select the trap with sufficient capacity when operating at lower steam pressures. reference full explanation of Safety Load Factors in Steam Traps Introduction section.\u003cbr\u003eWhen a temperature control valve is regulating flow to the process equipment, it is recommended to select a trap with a PMO that will exceed the inlet steam pressure to the control valve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFor Example:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eProcess application has a maximum steam inlet pressure of 100 psi, a maximum condensate load of 2,500 lbs\/hr and is discharging to a condensate return line with a possible back pressure of 25 psig.

All internal components can be replaced with the trap body remaining in-line. Repair kits include thermostatic air vent, float, valve seat and disc, and gaskets. The standard thermostatic air vent can be damaged by superheat; therefore, in applications with superheated steam, the thermostatic air vent should be replaced with a special “live orifice\" air vent.\u003c\/p\u003e\u003cdiv style=\"clear: both;\"\u003e \u003c\/div\u003e\u003cdiv class=\"tech\"\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv class=\"specs\"\u003e\n\u003cdiv class=\"column\"\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"left\"\u003eModel\u003c\/div\u003e\n\u003cdiv class=\"right\"\u003e\u003cdiv\u003eFTTS - Stainless Steel\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"left\"\u003eSizes\u003c\/div\u003e\n\u003cdiv class=\"right\"\u003e\u003cdiv\u003e1\/2\" - 1\"\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"left\"\u003eConnections\u003c\/div\u003e\n\u003cdiv class=\"right\"\u003e\u003cdiv\u003eNPT, SW, 150# FLG\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"left\"\u003eBody Material\u003c\/div\u003e\n\u003cdiv class=\"right\"\u003e\u003cdiv\u003e316 Stainless Steel\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"left\"\u003ePMO Max.
