The Next Generation of Ball Float Steam Traps: UNA 45, UNA 46 and UNA 46A – PN 40, CL300
Reliable. Flexible. Advanced.
GESTRA‘s new ball float steam trap features the proven rolling ball valve mechanism for smooth operation and tight shut-off in conjunction with a large number of different connections now up to DN 65 (2 ½“) and a new and leaner compact-type design. By repositioning the centrally located control unit it is easy to convert the UNA 4 at any time from horizontal to vertical flow and to change the flow direction from „left to right“ to „right to left“ in order to suit the pipework layout.
The various possibilities of installation of the UNA 4 make this ball float steam trap so flexible that it suits a wide range of applications. Other innovative new optional features that make the UNA 4 even more versatile are: an adjustable inner bypass, a strainer and the option to install electrodes directly inside the cover in order to monitor the performance of the steam trap and detect steam loss or banking-up of condensate.
The sleeve located at the outlet of the float trap is designed to center the control unit. The newdesign and the modified flow pattern downstream of the orifice bring about a considerable reduction of the flow velocity and, as a consequence, better protection of the valve body.
