SMARTVALVE
FOR FEEDBACK (CLOSED LOOP) CONTROL SCHEMES
Chlorinators’ new Model 7009 and Model 7010 SMARTVALVEs are highly sophisticated control valves for use wherever chlorine or sulfur dioxide is needed to treat varying water flow rates and/or varying water quality. These SMARTVALVEs: • Can be configured to operate in either of the following control schemes: flow proportional control, residual only control, compound loop control or feed forward dechlorination control. • Include a unique “linearization” program that assures the SMARTVALVE’s digital display reading matches the reading indicated on the gas feed system’s metering tube. • Can automatically compensate for changing system hydraulic “lag time” that occurs as the water flow rate increases and decreases. • Can operate with ORP monitors or residual analyzers. • Include an adjustable “deviation alarm” consisting of an LED and a relay that alerts operators when residual is too low or too high. • Include a residual “deadband” adjustment within which the controller will not make any corrections. This is to enhance the stability of the feedback control scheme. • Can be operated in the field four ways: fully automatic, electric/manual, and two (2) methods of manual. • Digital display and annunciator LEDs indicate: – Flow process variable in actual numbers or as a percent of flow. – Residual process variable in PPM residual or ORP value. – Valve plug position in pounds per day (PPD) of actual gas feed rate.
