Structural features
1. The working principle of the lever float steam trap is based on the density of vapor and liquid.
2. The valve body and bonnet are made of cast steel/forged steel.
3. 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.
4. Special flow channel design to achieve zero water hammer.
5. Patented flexible closing system and micron-level precision closing system double guarantee no steam leakage and long service life.
6. Built-in air exhaust valve to prevent steam lock.
7. The independent filter makes the trap work in a clean environment.
8. Choose diferent displacement curves according to the pressure.
9. The back pressure rate is as high as 95%
10. The drain plug is designed at the bottom of the trap to ensure that the internal water is removed after stopping, to prevented foating ball from freezing in cold weather.
