Rotary Valves

Welding Alloys’ solution

Welding Alloys uses a special Hardplate™ to protect the body shell and rotor of a rotary valve as these parts are exposed to severe wear. We provide the best option to prolong the lifetime of your rotary valve.


Compared with changing the body shell or the rotator with a standard one (not protected), Welding Alloys’s solution extends the lifetime of the production equipment up to three times and reduces maintenance downtime, production losses and costs.

Consistency and customer service

Our Integra™ engineers provide tailor made solutions ready to be installed and guarantee a consistent high-quality finish.
