The operating pressure acts in the direction of opening, so that the valve is opened fully. As the temperature of the condensate rises, the bimetallic plates deflect and pull the stage nozzle in the closing direction. Immediately below saturation temperature boiling pointthe duo stainless steel plates are deflected to such an extent that the orifice is almost completely closed.

In steam traps with GESTRA Thermovit regulators, the opening and closing process is controlled by the interaction of bimetallic plates and a stage nozzle. Thermostatic steam traps for removing condensate from steam or for venting steam pipes. Saturated steam pipes Superheated steam pipes Trace heaters Air heaters Thanks to automatic venting, steam traps from the BK series are also ideal for use as air vents.

However, the temperature-induced deflection of the duo stainless steel plates is not sufficient to generate the gestr force to counter the valve force acting on the nozzle needle in the opening direction throughout the entire operating range.

As the temperature of the condensate rises, the duo stainless steel plates deflect and pull the stage nozzle in the closing direction. Advantages Extremely good start-up performance No loss of steam Geztra for differential pressure up to bar Able to cope with the harshest operating conditions Any installation position — in horizontal or vertical pipes Inner parts made of corrosion-resistant stainless steel Can be serviced egstra removing the body from the pipe Metal base bushing provides the seal between the body and bimetallic regulator Stage nozzle for non-return valve action Wear-resistant.

Method of Operation The steam trap is fully open when the system starts up.

This way, thermal and spring properties are coordinated in such a way that the opening and closing temperatures are always just a few degrees below boiling point. Use Robust steam traps for condensate removal from heating processes with small load fluctuations.

The opening and closing process is controlled by the interaction of the stage nozzle and the temperature sensor, which consists of duo stainless steel plates. This state of equilibrium between the temperature-induced closing and pressure-induced opening forces determines the outlet cross section. Just below saturation temperature, the bimetallic plates are deflected to such an extent that the orifice is almost closed.

Thermostatic steam traps BK 45/46

Especially recommended for use in: When the system starts up and on the formation of cold condensate and air, the duo stainless steel plates lie flat. Therefore, the column of these plates consists of a spring with a characteristic that is adapted to the valve force, which changes under pressure. Especially recommended for use in:.

Be the first to review! It is precisely this principle that makes steam traps from the BK series highly responsive, very efficient and extremely resistant.

Robust steam traps for condensate removal from heating processes with small load fluctuations. Acting against this thermal process is the operating pressure and pressure that builds up in the chamber of the stage nozzle due to flash steam thermodynamic process.

The pressure in gdstra stage nozzle chamber therefore drops and, as the amount of flash steam declines, dissipates altogether. Cold condensate and air are discharged.
