Thermostatic steam traps BK 45/46

Just below saturation temperature, the bimetallic plates are deflected to such an extent that the orifice is almost closed. Immediately below saturation temperature boiling pointthe duo stainless steel plates are deflected to such an extent that the orifice is almost completely closed.

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 opening and closing process is controlled by the interaction of the stage nozzle and the temperature sensor, which consists of duo stainless steel gesra.

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

Bimetallic Steam Trap BK45, Steam Traps

This way, thermal geshra spring properties are coordinated in such a way that the opening and closing temperatures are always just a few degrees below boiling point. The pressure in the stage nozzle chamber therefore drops and, as the amount of flash steam declines, dissipates altogether. The operating pressure acts in the direction of opening, so that the valve is opened fully.

Robust steam traps for condensate removal from heating processes with small load fluctuations. Cold condensate and air are discharged.

gesta As the temperature of the condensate rises, the duo stainless steel plates deflect and pull the stage nozzle in the closing direction. When the system starts up and on the formation of cold condensate and air, the duo stainless steel plates lie flat. 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.

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 gestta the seal between the body and bimetallic regulator Stage nozzle for non-return valve action Wear-resistant.

Especially recommended for gestda in: Especially recommended for use in:. In steam traps with GESTRA Thermovit regulators, the opening and closing process is controlled by the interaction of bimetallic plates and a stage nozzle. This state of equilibrium between the temperature-induced closing and pressure-induced opening forces determines the outlet cross section.

BK 45/46 – Gestra

Thermostatic steam bk4 for removing condensate from steam or for venting steam pipes. It is precisely this principle that makes steam traps from the BK series highly responsive, very efficient and extremely resistant.

As the temperature of the condensate rises, the bimetallic plates deflect and pull the stage nozzle in the closing direction. Method of Operation The steam trap is fully open when the system starts up. Therefore, the column of these plates consists of a spring with a characteristic that is adapted to the valve force, which changes under pressure. Be the bk445 to review!
