The steam traps work independently of back pressure, thus ensuring universal application. The steam trap UNA 2.. features a body with bolted cover and a regulating unit. The component parts can be exchanged after removing the cover but without having to take the equipment out of the pipe (easy in-line maintenance). Different types of regulating unit are available for the steam traps. The regulating unit SIMPLEX is a level-dependent float-actuated control unit and particularly well suited for cold con- densate and superheated steam. The regulating unit DUPLEX is a float-actuated control unit for temperature-dependent and automatic deaeration of saturated steam systems. The regulating unit SIMPLEX-MAX is a level-dependent float-actuated control unit for large condensate flowrates and particularly well suited for cold condensate and superheate
