Designed specifically for rugged applications and processing of harsh and abrasive materials, the CI Series of rotary feeder valves provides bulk-material processing operations with continuous performance, reduced maintenance and optimal energy efficiency. The valve housings are cast to ensure strength, and the outboard bearing design of the CI Series extends bearing life and protects the bearings in high-temperature (up to 750ºF) applications. The CI Series design can easily manage applications with pressure differentials of up to 15 psig, and minimizes pressure loss throughout the system. The CI Series valves are available in cast iron or stainless steel (304 and 316), and available with a variable frequency drive to modulate drive speed and reduce power requirements. — ACS Valves Inc., Caledonia, Ont., Canada
