SHT1 Thermostatic (Film Box) Steam Trap

SHT1 Thermostatic (Film Box) Steam Trap

Description

Working Principle
  • The working principle of the bimetallic trap is to rely on the different temperature between saturated steam and condensed water.
  • When the set temperature is reached, the condensed water is continuously removed.
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 with heat treatment.The disc hardness is as high as HRC55,which improves the service life of the trap.
  • Imported bimetallic ensure precise temperature control.
  • The closing system adopts high-precision wire sealing structure.
  • Built-in filter makes the trap work in a clean environment.
  • The back pressure rate is as high as 50% or more.
