Rotary Valves: Design, Selection and Operational Issues

Rotary valves are widely used to feed pneumatic conveying pipelines, and for feed metering, explosion isolation, atmospheric isolation etc.  However there are literally thousands of combinations of different feature options available covering choice of materials of construction, rotor type, drive type, venting arrangements, bearing pattern, seal choice, clearances, cleaning features etc.  Faced with this bewildering choice, how does an engineer decide what to specify?  This course will help understand the reasons for the different options and how to choose them.

Topics will include:-

Application areas for rotary valves, and their different demands (feeding, explosion protection, isolation etc)
Basics of rotary valve performance – air leakage, feed rate etc
Materials of construction linked to issues of wear and build-up
Seals and bearings, options, functions and selection
Special consideration for explosion isolation
ATEX requirements and responsibilities
Features for cleaning and preventing contamination
Venting – needs, options and ensuring success
Review of practical application issues

This will be a classroom-based course but using a selection of components of different patterns for illustration, and many case studies of failures and successes to demonstrate the importance of correct specification.

Course fees are £490 per person.

Full course details and on-line booking is available at or ring Caroline Chapman on 020 8331 8646

This course is also offered as Day 3 of the Advanced Course: Pneumatic Conveying System Design on 5 - 6 December 2017. Please see website for details.
