SBT66 Pilot Inverted Bucket Steam Trap

  • The valve 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.

SBT66 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 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.
  • Install anti-water shock device, so that the fluid entering the valve bodydoes not produce water hammer phenomenon.
  • Built-in check valve, suitable for superheated steam environment.
  • Built-in filter allows steam the trap to work in a clean environment.
  • Select different capacity curves according to the pressure.
  • The back pressure rate is as high as 90% or more.
