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.

PATENT PENDING
REGAL MODEL 7009/7010 SMARTVALVE THEORY OF OPERATION Compound Loop Control A water flow meter with a 4-20 mA signal transmitter continually measures the amount of water flowing and transmits instantaneous signals to the primary input of the REGAL Model 7009 or 7010 SMARTVALVE causing the valve to feed the correct amount of chemical to the water based on the immediate dosage setting. At the same time, a residual or ORP analyzer draws a continuous sample of the treated water at the appropriate point downstream of the chemical injection point (after suitable mixing is achieved) and sends a proportional signal to the secondary input of the REGAL Model 7009 or 7010 SMARTVALVE based on the value of the actual residual measured. The controller circuitry in the SMARTVALVE compares the measured residual to the desired residual (operator established set point) and sends a timed correction signal to the SMARTVALVE motor driver circuitry based on the results of the analysis. If the analysis shows an actual residual greater than (or less than) the desired residual, the timed correction signal opens or closes the SMARTVALVE motor driver circuitry as necessary in an attempt to keep these two values the same.
