STD16 Thermodynamic (Disc) Steam Trap

STD16 Thermodynamic (Disc) Steam Trap

Description

Working Principle
  • Relying on the velocity difference between steam and liquid.
  • Exclude saturated condensate
Features
  • The valve body and valve bonnet are all made of forged steel.
  • The valve disc and valve seat are made of martensitic stainless steel. After heat treatment and aging treatment, they are not denatured and wear-resistant under high temperature and high pressure, which improves the service life of the trap.
  • Stainless steel insulation cover to isolate and slow down heat loss and eliminate invalid actions.
  • The fluid channel of the internal structure is designed strictly according to Bernoulli’s equation, and the structure is reasonable.
  • Built-in filter makes the trap work in a clean environment.
  • The back pressure rate is as high as 50% or more.
  • To exclude low temperature traps with large subcooling degree, it needs to be customized.
