Gas Flow Control Valve Automates Chemical Feed Process

May 19, 2010
The Capital Controls series 70CV3000 Chloromatic intelligent gas flow control valve is designed to control chemical feed in water or wastewater applications. The valve is said to eliminate the need for continuous operator monitoring and manual adjustment of the gas feed rate resulting from changes in flow and/or residual levels. Automation of the chemical feed process will yield a reduction in gas consumption for water and wastewater utilities, because manual system feed rates are based on peak process conditions. The valve is used in conjunction with a vacuum regulator, gas flow meter and an ejector to provide a complete disinfection system.
