Capital Controls® Series 70CV3000 Chloromatic™ Valve DatasheetSource: Severn Trent Services
The Series 70CV3000 Chloromatic™ Intelligent Gas Flow Control Valve is designed to control chemical feed in water or wastewater applications. The valve is wall mounted, responds to multiple process signals from a water flow transmitter and/or chlorine residual analyzer and is integrated with a microprocessor-based controller.
Automatic control eliminates the need for continuous operator monitoring and manual adjustment of the gas feed rate with changes in fl ow or residual, especially where chemical discharge levels are regulated. And since manual system feed rates are based on peak process conditions, automatic feed will reduce gas consumption. The integrated microprocessor-based controller eliminates the need for a separate controller to regulate your gas feed system. The intelligent valve is fi eld confi gurable for fl ow proportioning, residual, compound loop or feed forward control. Residual control is accomplished by a single-mode integral control loop with adjustable process lag time. All setup, tuning and control adjustment is achieved from the pushbutton panel.
Standard features include: built-in multiplier for feed forward control; automatic transfer from compound loop control when either the residual or fl ow signal is lost; bumpless transfer between manual and automatic control; digital vacuum fl uorescent display; alarm indication; user confi gurable alarm contacts; control contact inputs and a flow transmitter output signal.
