The new heavy-duty modular (HDM) and blowing seal modular (BSM) ranges from Rota Val have been designed using finite element analysis to make the valve housings even more robust. Where the valve feeds directly in to a conveying line, the BSM range has been designed to optimise product conveying and rotor pocket purge using computational fluid dynamics techniques.
The modular range will feature a new version of the successful rapid access design for quick cleaning. HDMF and BSMF fast clean versions have been designed with safety and ease of use in mind. The guide rails are a parallel design with an option for a rotor support tray, which makes servicing in difficult areas a much easier proposition.
The new RotaLign rotor centralising mechanism has been designed to optimise production time through a design that provides minimal downtime. The bearings can now be replaced during maintenance without the need to reset axial rotor clearances.
In addition to full ATEX certification, Rota Val has always hydraulically pressure tested each valve housing to ensure 100% casting integrity when supplying valves for explosion and flame containment applications.
