THE SCHOOL OF MECHANICAL ENGINEERING AT THE UNIVERSITY OF
WESTERN AUSTRALIA CARRIED OUT A SERIES OF RIGOROUS WEAR TESTS
ON ANVAL’S ROTARY FLOATING SHOE VALVE RANGE
The wear testing was conducted over a period of months by University of Western Australia (UWA) under-graduate and graduate mechanical engineers with the assistance of the Anval engineering team in order to establish wear rates and the operational capacity of the RFS valve.
The RFS range of rotary airlocks and feeders has been in existence for over ten years, initially being produced by Anval’s sister company, Ansac. However, in order to conclusively prove the durability of the valve range, Anval decided that an objective third party would be invited to conduct prolonged wear testing and author a technical paper on the results.
The testing focused on the ceramic and cast iron interface unique to Anval’s RFS range of valves. The ceramic ‘tipped’ rotors have been designed to maintain continuous contact with the hardened SG cast iron floating shoe, ensuring an adequate seal between the inlet and outlet flange.
This interface is subjected to a constant level of wear as the rotor turns during normal operation. The amount and rate of interface wear has then been microscopically analysed by the engineering teams, confirming the durability of the RFS valve.
The extensive testing of the interface involved subjecting the valve to various types of material flow with varying degrees of abrasiveness. This enabled Anval to establish accurate data confirming the low wearing properties of the construction materials selected for the valve construction; utilizing ceramics and cast iron floating shoe.
"RFS Valves can be used to transporteven the most aggressive product and
still have a life cycle of years instead of months."
"The final report has proven that the ceramic tipped rotor in contact with the hardened SG cast iron shoe allows the rotary feeder to efficiently traverse all manner of materials with a minimum of wear” explained Mr Brian Ging, Sales Representative for Ansac and Anval within Australia.
“Therefore, the RFS can be used to transport even the most aggressive product and still have a life cycle of years instead of months.”
“The results are as we predicted. We always knew the RFS was a far more durable unit than a standard rotary valve, and now we have the data and report to prove it.”
