DMN-WESTINGHOUSE MLD 400 rotary valves have proved to be the pick of the crop for major vegetable processing plants. Vak Conveying Systems of Marple, Cheshire designed and installed the waste product removal systems for Marshall’s, Lincolnshire Field Products and Exotic Farm Produce all situated in Lincolnshire, the county that produces most of the UK’s high quality vegetables.

Vak Systems is a family owned and run firm, with a growing reputation and a blue chip client list. They specialise in the design and installation of pneumatic conveying systems and in this case their specific task was the efficient removal of waste materials from the processing plants. After assessing a range of competing valves they chose the DMN MLD 400 rotary valve as the vital component in their systems.

In the past, waste removal systems had been little more than a belt conveyor, which led to spillage, rotting vegetation and the inevitable smell and fly problems. With Vak’s pneumatic conveying system, the removal is completely enclosed and waste can be dispensed directly into trailers for use in animal feed. The original idea for the design came to Director Steve Wild as he was using a garden blower/vacuum to get rid of leaves on his lawn at home. “Needless to say, our system had to be rather more robust,” he comments. “It has to deal with all types of material including cabbage butts the size of dinner plates. Even things like chopping knives and pieces of wooden pallet sometimes accidentally get into the line but the MLD 400 has no problem dealing with anything.”


Robustness and reliability were the two major factors, which determined Vak’s choice of valve along with the excellent back-up given by DMN-WESTINGHOUSE.
