These float and thermostatic traps are used for lower pressure HVAC and light industrial process applications. They are used on unit heaters, water heaters, pressing machines, heat exchangers and coils. For drip applications, such as draining steam mains and steam supply lines, use 3\/4\" FT-075 (FT73-075-13-N). F\u0026amp;T traps have excellent air-handling capability, which make them a better choice than Inverted Bucket traps for most process applications. FT Series traps have a dual inlet-outlet H-Pattern connection allowing for additional flexibility in installation.\u003c\/p\u003e\u003ch2\u003eSelection \/ Sizing \/ Capacities\u003c\/h2\u003e\u003cp\u003eSelect a model that can handle the maximum working pressure of the steam system. For example, the FT3-015 has a maximum working pressure of 15 PSI. Consult capacity tables to properly size unit. Available in 3\/4\" through 2\" NPT connections. Select these models for steam systems with maximum working pressure of 75 PSIG. The maximum operating pressure (PMO) rating of model selected must meet or exceed the maximum steam pressure or the trap may not open. For example; the FT-35-030 has a PMO of 30 psi. For drip applications, a 3\/4\" FT size is 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 a safety margin is applied in order to select a trap with sufficient capacity at lower pressures.

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\u003eInstallation \u0026amp; Maintenance\u003c\/h2\u003e\u003cp\u003eThe trap must be installed upright and level for the float mechanism to operate properly. All internal components can be replaced with the trap body piped in-line.
