Working in an exclusive collaboration with Fike, the market leader in explosion protection, we have designed and built some large 1×1.2m explosion isolation valves that are currently being tested by Ineris for Atex certification as a protective device. The valves are used as part of an explosion detection, suppression and isolation system. The challenge was to get the 135kg slide plate closed in under 300ms without destroying the valve. Fike have use computation fluid dynamics to model a…

MID’s product line is not limited to standard valves or variations on standard- we manufacture one-off designs for customers on a regular basis. Cemex Rugby plant needed a replacement for their main silo outloading valves that feed the cement tankers you see driving around the country delivering their product. The existing units were a little agricultural- bent steel thin section plate, big unmachined gaps and rubber seals that wore away leading to cement flushing through…

Datasheet   We used 3D CAD software to model the way the cleaning paddle is driven by the main rotor for a rotary valve handling sunflower seeds which leave an oily deposit in the rotor, eventually blinding it and preventing any further product from getting through the valve. The components were laser cut from the CAD model, fabricated and assembled with some fitting to make the gears run smoothly and quietly. All 10 units went together smoothly with…

 BD damper datasheet Here’s a 1000mm bore fully stainless steel 316 custom designed damper valve with EPDM O ring seals. Designed to handle fume laden air, the body is fabricated from rolled plate then machined to give a smooth finish. The drilling is custom made to match the surrounding ductwork, the shafts are mounted in maintenance free bronze bearings to give exceptional longevity with no maintenance. The client asked us to mount their own large,…

We don’t just repair our own rotary valves. If you have a worn out unit from another manufacturer then we can, within reason, repair them to “as new” condition or even improve on the original unit by fitting hard faced components. The initial assessment is free of charge- just send the cleaned unit back to us and we will: Examine and measure the valve Generate a repair report and a fixed repair price If it’s…

Now a standard product Something a little different- a rotary valve with a scraper unit for sticky materials. The valve is based on our standard MV 500 rotary valve but the rotor is a custom made unit with specially scalloped pockets. The geometry is carefully designed to that a simple scraper, powered by synchronised gears on the end opposite the motor. For every 1/6 rotation, the scraper pulls any stuck material out of the bottom of…
