Very simple internal structure steam trap, all stainless steel, what makes it highly resistant to corrosion and water hammer. The steam trap valve controls the discontinuous condensate discharge, and also the evacuation of air and non-condensable gases through the vent hole; which also is used as the control steam outlet. The UIB 20 / UIB 40 steam trap must be installed in vertical position. This steam trap is connected to the TVS by 360º universal connector.
