Series 70CV3000 Chloromatic 3000 gas-flow control valve

The Series 70CV3000 Chloromatic 3000 gas-flow control valve is a wall-mounted system designed for automatic control of chemical feed in water or wastewater applications. The integrated, microprocessor-based controller has a control valve that responds to multiple process signals from a water flow transmitter or chlorine residual analyzer. The Chloromatic 3000 eliminates the need for continuous operator monitoring and manual adjustment of the gas feed rate resulting from changes in flow and/or residual levels. Automating the chemical feed process typically leads to a reduction in gas consumption for water and wastewater utilities, since manual feed rates are based on peak process conditions. The Chloromatic 3000 is field-configurable for flow proportioning, residual, compound-loop or feed-forward control. While it features ten range capacities from 10 to 3,000 lb/d (up to 60 kg/h) for chlorine, it is also suitable for use with sulfur dioxide, ammonia and carbon dioxide. The system comes standard with an 11-step calibration of the valve plug that yields a true gas flow retransmission signal and eliminates the need for a separate linearized D/P transmitter. The Chloromatic 3000 is used in conjunction with a vacuum regulator, gas flowmeter and an ejector to provide a complete disinfection system.
