FLOAT & THERMOSTATIC TRAPS - HOW IT WORKS

Float & Thermostatic steam traps are the most common trap type used for process applications. They use a float-operated valve mechanism to discharge condensate as it is formed, and an air vent for discharging air at start-up; both very important requirements for process applications. Venting Air Prior to the steam being turn on the piping system, heat exchanger and trap are filled with air which is much cooler than steam. The thermostatic air vent will be in the wide open position. During startup this air will be pushed through the air vent by the incoming steam into the condensate return line. Discharging Condensate When condensate enters the trap, the float lifts which opens the valve, allowing condensate to discharge. Closed (Trapping Steam) When steam is present, and no condensate is entering the trap, the valve and thermostatic air vent remain closed, trapping steam in the system.

THERMODYNAMIC STEAM TRAP - HOW IT WORKS

Thermodynamic Steam Trap Thermodynamic traps have only one moving part, the valve disc, which allows condensate to be discharged when present and closes tightly upon the arrival of steam. These traps have an inherently rugged design and are commonly used as drip traps on steam mains and supply lines. Their solid construction and single moving part make them resistant to waterhammer and are freeze-proof when installed vertically. Thermodynamic traps will only discharge small amounts of air and therefore are typically not used in process applications Valve Disc Open When condensate is present, trap remains in the open position allowing condensate to discharge. Steam pressure pushes the condensate thru the trap. Valve Disc Starting to Close When steam enters the trap, it creates an internal pressure above the disc that instantly forces the disc and seat to close tightly, preventing steam from escaping. Valve Disc Closed Steam pressure above the disc holds the disc closed, trapping steam in the system. Trap will remain closed until the steam above the disc condenses, due to heat loss through the cap.
