STD80 Thermodynamic (Disc) Steam Trap

STD80 Thermodynamic (Disc) Steam Trap

Description

Working Principle

Relying on the velocity difference between steam and liquid.

Features
  • The valve body and valve bonnet are all made of forged steel.
  • The valve disc and valve seat are made of special stainless steel, which
    is heat treated and aging treatment, no deformation and wear
    resistance under high temperature and high pressure, improve the
    service life of the trap.
  • Stainless steel insulation cover to isolate and slow down heat loss and
    prevent the trap from emptying up phenomenon.
  • 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.
