SBT40 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.

SBT40 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 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.
  • U-shaped runner design achieves water sealing effect without leakage of steam.
  • Flexible closing system with patented technology, no steam leakage.
  • Install anti-water shock device, so that the fluid entering the valve body does not produce water hammer phenomenon.
  • Built-in check valve, suitable for superheated steam environment.
  • Built-in filter allows the trap to work in a clean environment.
  • Select different displacement curves according to the pressure.
  • The back pressure rate is as high as 90% or more.
  • After stopping, the screw plug can be opened to drain the condensed water to prevent damage to the trap due to low temperature freezing.
