Air Trap AFT10A

Air Trap AFT10A

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.
  • Pressure equalization pipe completely solves the air blockage.
  • Built-in filter makes the air trap work in a clean environment.
  • Choose different capacity curves according to the differential pressure, increase capacity.
  • Drain plug is designed at the bottom of the air trap to ensure that the internal water will be drained, to prevent floating ball from freezing damage in cold weather.
Technical Standard
  • ISO 6553: Automatic steam traps – Marking
  • ISO 6554: Automatic steam traps -Face-to-face dimensions
  • ISO 6948: Automatic steam traps -Production and performance
