The CS49H disc steam trap utilizes the thermodynamic properties of a second evaporation that occurs when condensate discharge is low, and there are differences in viscosity, sealing, etc. with respect to steam to drive the actuator. With steam or air insulation device, not affected by the ambient temperature, reduce the frequency of action, and extend the life. Equipped with a filter and drain. The valve action is sensitive and reliable, large drainage capacity. Suitable for high temperature steam main line and superheated steam pipe network of the steam blocking drainage.
Structural Characteristics
The CS49H disc-type steam trap features a rational design, compact size, light weight, and easy installation. It is freeze-resistant, withstands water hammer and superheating, incorporates a stainless steel filter for convenient maintenance, offers responsive operation, excellent sealing performance, and extended service life.
Working Principle
The CS49H disc-type steam trap utilizes the differing thermodynamic properties of steam and condensate—specifically changes in velocity and volume as they pass through the valve orifice—to drive the disc plate, opening and closing the seat orifice. This mechanism achieves steam blocking and condensate drainage.
