1, with steam or air heat units, independent of ambient temperature influence, reduce the operating frequency, extending life. 
 2, equipped with filters and sewage. 
 3, the valve is sensitive and reliable, large displacement. 

 Two, CS19H thermal steam trap (Y) works: 

 CS19H, CS69H, CS49H thermal steam trap (Y) is the use of thermal dynamics, when the condensate drain is low, evaporation will occur the second time, and viscosity, and vapor sealed so there differences driven hoist pieces.
