Tiled TWA liner  Atex


We use the latest in ceramic lining technology to make rotary valves last an incredibly long time.

Other manufacturers cast their linings onto the valve- this limits the hardness achievable when high temperature firing is required to achieve maximum hardness of the lining, instead we tile our valves using a custom made ceramic adhesive with excellent thermal properties. Then we diamond grind both rotor and body to an extremely fine finish.

The tiles we use are not glazed but hard all the way through. They're 92% alumina which is resistant to all but the very hardest of materials- diamond.
