Ball Float Steam Trap Manufacturer in INDIA:

Specialityvalve is a leading Ball Float Steam Trap Manufacturer In INDIA.   Mechanical traps, such as Ball Float Steam Traps, are a type of mechanical trap. They work by using the density difference between steam and water. A lever connects a ball float to the valve and seat. When the condensate within the trap reaches a certain amount, it will be discharged. Condensate is constantly discharged. Ball Float Steam Traps may be used in any process application where condensate must be extracted as soon as it forms, such as all types of heat exchangers, tank and unit heaters, and others. The type GC1 is specifically designed for applications in the food, pharmaceutical, and other industries that require stainless steel bodies and small condensate loads. It can also be used to drain the main lines of steam.


  • Body material: Carbon steel, cast steel (WCB, WCC, LCC, WC6, LCB, WC9), stainless steel (SS316, SS304, CF8), ductile iron.
  • Class: 150 to 2500.
  • Size: ¾” – 4”.
  • Ends: Socket weld butt weld, flanged, threaded.

The thermostatic air vent rapidly discharges air during start up (membrane or bimetal type). The steam trap body is filled with cold condensate. The float rises and opens the valve when a certain water level is reached. The open valve and the open air vent are used to discharge the cold condensate. The air vent shuts when the condensate reaches saturation temperature, and the condensate is only discharged through the main valve orifice. Inside the trap body, the condensate forms a water seal, preventing live steam loss at all times.

The water level within the trap body controls the valve’s opening degree. Condensate is constantly discharged. The temperature cools slightly as air reaches the trap and accumulates at the top of the trap body, and the air vent, which opens slightly below saturation temperature, starts to discharge the air from the trap.


  • For a long and trouble-free service, all traps are fitted with stainless steel wear and corrosion resistant float, lever, valve, and seat systems.
  • Each ball float steam trap has an air vent that allows air and gases to escape during start up and operation.
  • All traps are made to be simple to clean and maintain.

The difference in density between steam and condensate is sensed by the ball float style trap. Since the valve is still flooded, neither steam nor air may pass through it, early traps of this kind relied on a manually operated cock at the top of the body to vent.
