Structural features
 1. The working principle of the inverted bucket steam trap is based on the difference of vapor and liquid density.
2. The valve body and bonnet are made of forged steel/cast 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. U-shaped flow channel design realizes water sealing effect without leaking steam.
5. Patented flexible closing system, no steam leakage.
6. Equipped with a water-proof device so that the fluid entering the valve body will not produce water-hammer.
7. Built-in check valve is suitable for superheated steam environment.
8. Built-in filter makes the water valve work in a clean environment.
9. Choose different displacement curves according to the pressure.
10. The back pressure rate is as high as 90%.
11. The screw plug can drain the condensed water after stopping to prevent damage to the trap due to freezing or low temperature.
