High Pressure Thermodynamic Steam Trap, ISO 6552, ASTM A105

Product Name: High Pressure Thermodynamic Steam Trap
Design Standard: ISO 6552
Body Material: ASTM A105
Size: Custom
Pressure: Custom
End Connection: Threaded
Medium: Steam Condensate

The high-pressure thermal steam trap operates based on thermodynamic principles, utilizing the differences in flow rate and volume between steam and condensate. As these fluids pass through the valve orifice, the resulting pressure and velocity changes drive the valve disc to open or close the seat, effectively separating steam from condensate. According to Boergli’s thermodynamic theory, the distinct behaviors of steam and condensate create dynamic and static pressure variations, both kinetic and potential, which generate a pressure differential across the valve disc. This differential causes the disc to actuate, achieving reliable steam trapping and condensate discharge. The CS69Y is widely used in high, medium, and low-pressure steam pipelines and steam tracing systems.
