Stainless steel series
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.
Please inquire about your desired rotary union directly here:
Request infos on our contact page or alternatively fill out the rotary union project questionnaire.
Material
Housing: stainless steel
Shaft: stainless steel
Media/hydraulic fluids
Hydraulic oil,
compressed air,
vacuum,
Water on request
In case of different media,
we recommend providing a channel as a leakage line.
Example
There will be two channels
for compressed air and
one channel neede
for hydraulics
Recommendation:
4-channel rotatory union
