Students and researchers at the Wolfson Centre for Bulk Solids Handling Technology, Greenwich University, are set to benefit from a highly practical contribution by Vortex Valves.
The university has installed a Vortex Roller Gate valve, donated by the company, on the receiving hopper of a pneumatic conveying test rig. The rig measures conveying properties of a very wide range of powders, often as part of industrial research projects.

Professor Mike Bradley approached Vortex’s UK office in Darlington after encountering repeated blocking problems with an existing valve in the test rig. He explains: “When the 8” butterfly valve was open, the dimension between the wafer and the side of the bore was only a little over three inches, so it would contribute to hold-up with only mildly cohesive powders.This led to applying aeration and “manual percussive therapy” of the hopper to get flow moving.”
The replacement valve was required to fit straight into the system, in the footprint of the butterfly valve. Vortex responded by supplying a 10” Roller Gate, with custom-built 10” square to 8” round transitions to allow it to fit straight into the existing pipe-work. The upper transition also incorporated a special service inlet that ensured material flow was diverted away from seals and components. This greatly extends the life expectancy of the valve.
Jon Naylor, European Managing Director for Vortex Valves said: “I was extremely pleased to be able to help out the Wolfson Centre in this case. I’m happy we have provided them with a versatile and long lasting valve that will serve them well for many years to come.”
