GESTRA UNA 4 ball float steam traps cannot fail to impress, with their simple, modular design that makes them perfectly flexible in use.

The modular design means that the steam trap’s direction of flow can be varied. With a total of 33 different options for installation in the pipe (11 types of connection for each direction of flow – vertical, horizontal to the left and horizontal to the right), these traps fit every pipe. The materials and design of the forged body conform to EN and ASME standards
