Large Valves with Atex Certification

The Right Valve for the Right Job

Industry: Feed Processing

The problem:

  • Our customer was looking for a large Rotary Valve to handle up to 100,000 kilograms of animal feed an hour.
  • Because of the environment that the valves would be installed in, they were required to be ATEX category 3 certified.

The requirement:

The solution:

  • Our 750mm rotary valve running at 12rpm could handle this volume with ease. We fitted a ten vane rotor with adjustable, abrasion resistant tips and stiffeners to provide tight tolerances.
  • Together with an ATEX certified motor, the valve is certified for zone 20 internally and zone 22 externally.

The result:

Working in collaboration, creating tailored solutions, engineered for safety.
