SBT50 Pilot Inverted Bucket Steam Trap

  • The body and cover are made of cast steel.
  • The internal parts are all made of stainless steel, and the wear allowance has been fully considered in the design of the movable parts, which improves the service life of the trap.

SBT50 Pilot Inverted Bucket Steam Trap

Description

Working Principle

.Based on the differential density of steam and liquid.
.the main valve is guided to open through the pilot valve, and the capacity is large.

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 steam trap due to low temperature freezing.
