Most rotary valves on the market today are proficient with air sealing and pressure holding but far from being contamination proof. Scheduled cleaning is time consuming and troublesome because of the exposed supporting bearing at both ends of rotor. They are also bulky and heavy due to traditional sand casting and welding methods.
Sirius Technology’s new sanitary rotary valve’s patented revolutionary design challenges these problems with unique solutions.
The Value-Added Patented Features
