| Inverted Bucket Steam Traps belong to the family of mechanical traps. They operate on the difference in density between steam and water. MIYAWAKI offers a very wide range of inverted bucket steam traps for small up to large condensate loads. |
Inverted bucket steam traps discharge the condensate intermittently.
Types:
| ES | Cast Iron Inverted Bucket Steam Traps for small up to medium condensate loads | |||
| ESU | Stainless Steel Inverted Bucket Steam Traps for small up to medium condensate loads | |||
| ER | Cast Iron Inverted Bucket Steam Traps for medium up to high condensate loads | |||
| ESH, ER25 | Cast Steel Inverted Bucket Steam Traps for high pressure and small up to high condensate loads |

1&2
On start-up the bucket is down and the valve is open. Low temperature condensate and air, later high temperature condensate enter the trap. The condensate fills the bucket and the trap body completely. As the bucket is completely submerged in the water, it lies on the bottom of the trap, the valve is wide open and condensate will discharge.
3&4
Steam enters the trap under the bottom of the bucket. The more steam is entering the trap, the more it collects at the top of the bucket, causing the bucket to move upwards (buoyancy of the bucket inside the water). At the top position of the bucket the valve will close the seat.
5&6
Air and gases pass through a small hole in the top of the bucket and collect at the top of the trap. Steam is also passing through the hole and condensing. When more condensate is entering the trap, the bucket will loose its buoyancy and will move down. The valve will open and condensate will discharge.
