SFT10A Lever Ball Float Steam Trap

Description

Working Principle

Based on the density of vapor and liquid.

Features
  • The 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.
  • Built-in air exhaust valve to prevent steam lock.
  • The independent filter makes the trap work in a clean environment.
  • Choose different displacement curves according to the pressure.
  • The back pressure rate is as high as 95%
  • The drain plug is designed at the bottom of the trap to ensure that the internal water is removed after stopping, to prevented floating ball from freezing in cold weather.
