Which rotary valve materials are best for handling highly abrasive chemicals?

A rotary valve’s housing is typically made from cast iron or various grades of stainless-steel, but when you process highly abrasive chemicals, internal coatings can add a much-needed layer of protection that extends the valve’s lifespan. XTR-Coat is an excellent choice for its strong resistance to corrosion and abrasion, as well as its non-stick surface. For even more abrasive materials like silica sand, a tungsten coating offers the best durability.
