Implemental Stainless Steel Thermodynamic Steam Trap (3/4 Inch) Check Valves

The steam trap works on the pressure difference, above and below the disc. Disc is raised from its seat due to incoming pressure. High velocity of flashing condensate create low pressure beneath the disc, at the same time pressure is build up in the chamber that force the disc on the seat. Now the condensates in the chamber decrease the pressure and when it is lower than the inlet pressure, the disc lifts. This cycle repeats again and again.
