1″ CB/ST UNION Left
This Rotary (C.B.) Union is fitted with an Adaptor suitable for double flow with a stationary centre tube. This gives flow areas through the centre
tube and annulus. Centre tubes are only provided if ordered. The centre tube is fixed to the Rotary (C.B.) Union end by means of a screw
thread shown as dimension ‘O’. Flow can pass in through the centre tube and return through the annulus or be reversed.
For steam applications, a typical example of which is shown on page 3, the centre tube is curved to reach the condensate in the bottom of the
cylinder. At times the roll neck diameter to length ratio prevents a curved tube being used, in such cases we can provide a Syphon Elbow
