1/2″ PB/RS UNION Right

Type R.S. – Double Flow (Rotary Center Tube)
Fitted with an elbow suitable for a rotating center tube (which must be located and driven by the machine). The center tube – provided only if ordered – rotates in a labyrinth bush. Flow can pass in through the center tube and return through the annulus or be reversed. The center tube “sealing” system allows for a slight internal leakage between the supply and return lines. If these fluids must not mix, alternate designs are available.

The rotary P.B. union has been developed from the rotary R.E. union and utilizes the same well-proven and highly successful bellows seal and bearing system. The body is manufactured from de-zincification resistant brass which has advantages over conventional brass and the cast iron adapter of the rotary R.E. union, especially for water cooling applications.
