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

BK 45/46 – Gestra

Especially recommended for use in:. The pressure in the stage ggestra chamber therefore drops and, as the amount of flash steam declines, dissipates altogether. 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.

Thermostatic steam traps for removing condensate from steam or for venting steam pipes. Immediately below saturation temperature boiling pointthe duo stainless steel plates are deflected to such an extent that the orifice is almost completely closed. This state of equilibrium between the temperature-induced closing and pressure-induced opening forces determines the outlet cross section.

Method of Operation The steam trap is bk455 open when the system starts up.

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. 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 Suitable 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 without 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.

Thermostatic steam traps BK 45/46

Especially recommended for use in: It is precisely this principle that makes steam traps from the BK series highly responsive, very efficient and extremely resistant. In steam traps with GESTRA Thermovit regulators, the opening and closing process is controlled by the interaction of bimetallic plates and a stage nozzle.

As the temperature of the condensate rises, the bimetallic plates deflect and pull the stage nozzle in the closing direction. The operating pressure acts in the direction of opening, so that the valve is opened fully. When the system starts up and on the formation of cold condensate and air, the duo stainless steel plates lie flat.

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.

The opening and closing process is controlled by the interaction of the gesfra nozzle and the temperature sensor, which consists of duo stainless steel plates. Just below saturation temperature, the bimetallic plates are deflected to such an extent that the orifice is almost closed.

Robust steam traps for condensate removal from heating processes with small load fluctuations. Use Robust steam traps for condensate removal from heating processes with small load fluctuations.

Therefore, the column of these plates consists of a spring with a characteristic that is adapted to the valve force, which changes under pressure.
