Chemical industry FAQs
You asked, we answered these common questions related to the chemical processing industry and rotary valves.
See all FAQs-
A.
To ensure the best possible lifecycle, safety, and performance in chemical processing environments, rotary valves should be inspected and maintained regularly. Keep spare parts on the shelf to minimize downtime, particularly rotors, shaft seals, and bearings. These are all essential in preventing leakage and ensuring reliable flow of chemical ingredients.
Relevant for: Technical Support, Reliability -
A.
Leakage can happen when rotary valve parts wear down, particularly with abrasive or corrosive chemicals. The most important parts to check and maintain regularly are rotors, shaft seals, and bearings. Anti-corrosive coatings such as XTR-Coat can prevent rotor-to-housing tolerances from wearing down too quickly, which is a key aspect of preventing leakage. Four-lobed shaft seals last longer and have a more reliable seal. Finally, outboard bearings have a longer service life and lower risk of failure.
Relevant for: Difficult Products, Safety -
A.
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.
