Ball float steam traps

Ball float steam traps.

Mechanical condensate drain. The principle of operation of these steam traps is based on the difference in density between water and steam.

Ball float steam traps, in which the float is connected by a lever to the valve and seat. Condensate is drained continuously when the condensate reaches a certain level in the float chamber. Air is vented during start-up through a thermostatic air valve (capsule or bimetal).

Specifications:

  • Large capacity steam traps such as G2-G8, GH2-GH8 are equipped with a double counterbalanced valve which provides high condensate capacity in a small size;
  • Stainless steel float, lever, valve and seat for long and reliable operation;
  • Air valve for venting air and non-condensable gases during start-up and operation;
  • The thought-over design allows to make service without removal from the line;

Application:

Ball float steam traps are installed on all types of equipment, such as heat exchangers, heating tanks, etc., where immediate condensate drainage is required.

The GC1 is specifically designed for applications in the food, pharmaceutical and other industries where small volumes of condensate need to be drained and where stainless steel fittings are required. This model is also suitable for draining steam pipes.

Principle of operation: 

When the system is started, air is vented through a thermostatic air valve (capsule or bimetal). Cold condensate filling the body of the trap raises the float and the valve opens. In this case, cold condensate is discharged through the main and air valves.

The inflow of hot condensate close to the saturation temperature leads to the closing of the air valve and the condensate discharge continues only through the main valve. Maintaining a constant minimum level of condensate in the trap ensures that no steam escapes.

The degree of opening of the main valve is controlled by the level of condensate in the trap body. Condensate is drained continuously. If air enters the trap, the temperature in the trap drops below saturation temperature and the air valve opens, venting the trap.
