SBT30 Inverted Bucket Steam Trap

Description

Working Principle

Based on the differential density of steam and liquid.

Features
  • The valve body and valve cover are all made of forged steel/cast steel.
  • Internal parts are all made of stainless steel and added with anti-wear allowance, extend trap life.
  • U-shaped flow channel design, to achieve water sealing effect, no leakage of steam.
  • Reliable flexible closure system with patented technology, no steam leakage.
  • Install anti-water hammer device.
  • Built-in check valve, suitable for superheated steam environment.
  • Built-in filter allows the steam trap to work in a clean environment.
  • Select different capacity curves according to the pressure difference to increase the capacity
  • The back pressure rate is as high as 90% or more.
  • After the steam is stopped, the condensed water can be removed by opening the screw plug to prevent damage to the trap due to low temperature freezing.
