Improving Our Equipment to Meet Your Needs

Industry: All Industries

The Application:

  • To provide multiple valves to process abrasive torrefied pellets 24 hours a day 365 days per year with minimal air loss across the units.

The requirement:

  • To provide a valve that would meet ST2 (10bar) explosion certification, handling an abrasive product whilst maintaining the desired air lock. The valves would be subject to intensive maintenance process and so needed to be extremely robust yet simple to maintain.

The solution:

  • Working hand in hand with our customer Rotolok developed an all new version of its class leading 600mm Rotary Valve. This involved laying down new casting patterns for the main body and covers alongside other critical design features. Casting thicknesses were increased in all key areas by 25%. The rotor shaft diameter was increased by 75% and the bearings were uprated.

The result

  • An extremely robust valve that can handle all that is thrown at it and continue to operate at maximum efficiency. A happy customer so pleased they have since placed repeat orders for multiple units.

I just wanted to say thank you for the help and support you recently provided on a very urgent enquiry. One of my customers needed a rotary valve manufactured and delivered within just a few days.
