DOUGLAS Steam Traps
Inverted-Bucket Steam Traps
- Sizes: 1/2" to 1" [15mm to 25mm]
- Maximum operating pressure: 1,015 psig [70barg]
- Materials: Carbon steel, stainless steel, and alloy steel
OPERATING PRINCIPLE
is based on the different density between steam and condensate. The float is an open and inverted bucket. Condensate enters the trap from the bottom and inside the bucket that is connected to the valve through a lever. Condensate completely fills the trap and is discharged through the valve. Steam and air entering the submerged bucket causes it to float on the surrounding condensate thereby closing the discharge valve. Air discharge is
ensured by a vent hole in the upper part of the bucket while steam condenses (and partially through the air vent). The bucket will sink again ( and open the valve) when condensate reaches a level where the weight of the bucket overcomes the pressure acting on the valve.
