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

SFT40A Lever Ball Float Steam Trap

Description

Working Principle

Based on the differential density of steam and liquid.

Features
  • Valve body and bonnet are made of cast steel, forged steel.
  • All internal parts are made of stainless steel, and the wear allowance has been fully considered in the design of movable parts, which improves the service life of the steam trap.
  • Special flow channel design to achieve zero water hammer.
  • Patented flexible closing system and micron-level precision closing system double guarantee no steam leakage and long service life.
  • Built-in filter makes the steam trap work in a clean environment.
  • Choose different capacity curves according to the differential pressure.Back pressure rate is as high as 95%.
  • Drain plug is designed at the bottom of the steam trap to ensure that the internal water will be drained, to prevent floating ball from freezing damage in cold weather.
