Description

Pressure Rating : 1.*- 6.4Mpa 
Specification: DN****0
Material: cast steel 
Standard flanges:  DIN   ANSI  JIS  JB*9 
Structural characteristic
1.Attached with steam or air heat preservation mechanism and unaffected by the environmental humidity;with operation frequency decreased and service life prolonged.
2.Provided with filter screen and drainage valve .
***** valve runs flexibly and reliably with large displacement.
Working principle:
By taking advantage of themodynamics characteristics, secondary evaporation will arise when the condensate water is discharged to the lower pressure zone and meanwhile when the viscosity and density of steam differ, the drain valve will open of close.
