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 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.
