Transmin has been the exclusive Australian distributor for Rotaval rotary valves, blow seals and diverter valves for over 20 years.  From bulk minerals handling to the finest of industrial materials, RotaVal has a rotary valve solution for your application.


The HDMC Rotary Valve is a cost effective solution based on the HDM valves for occasional cleaning of the internal valve.  The non-drive end cover can be quickly removed to gain access for cleaning which can be carried out by plant operators without the need for special tools.


Various standards of finish are available to suit most hygienic applications.  However for more stringent requirements and frequent cleaning consider the HDMF fast clean rotary valve.  With the design being modular and the cleanable range incorporating a tapered rotor, this valve can be converted into a fast clean version (HDMF) by simply retrofitting guide rails and the Rotalign™ (GB Patent No. 2 522 293) bearing assembly, which is our self-centralising rotor design.
