SHT32 Thermostatic(Bimetallic)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 body and cover are all made of forged steel.
  • The disc and 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.
  • 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 80% or more.
