The stainless steel variant of the rotary union or rotary distributor series is particularly suitable for water/cooling water, hydraulics or the outdoor area, as well as for higher pressures.

Executions:
Rotary distributors are subdivided according to the number of their channels and according to the nominal width or the connection thread:

Number of channels available: 1, 2, 4, 6 and 8
Connection sizes:                         M5 to G 1″ (see individual series)

General:
The values ​​given below are the maximum parameters that can be achieved.
Technical advice is required when using below 0 °C or when several parameters coincide in the limit range.
