Durability of Rotary Valve Reveals What Your System is Made of

By Tom Hobson

When choosing a rotary valve for your dry solid material handling application, durability is paramount. A recent article published on powderandbulk.com emphasized the importance of using a rotary valve that is constructed of highly wear-resistant material that can withstand abrasive minerals and metals such as silica sand, china clay, cast iron swarf, fly ash, grain, slate dust, petro-coke and granite dust. A rotary valve is key to controlling the feed or discharge of free-flowing bulk material without compromising the negative or positive air pressure used in the system. Since rotary valve replacement can be expensive and time-consuming, it’s important to implement a superior product from the beginning. Rotary valves fabricated from heavy duty steel plates like the Rhino Rotary H Valve™ provide exceptional performance and reliability in handling extremely abrasive materials when compared to competing cast valves. Available in custom sizes, this rugged rotary valve has hardened-surface rotor vane tips and added clearance outside the rotor shroud that allow it to operate smoothly without packing or excessive wear.
