Regal Chlorinators – 7007 – Smartvalve, Step Rate Control, 1000 or 2000 PPD

The Regal Chlorinators 7007 Smartvalve, Step Rate Control, 1000 or 2000 PPD automatically regulates the gas feed rate needed to maintain the chemical residual level determined for a specific water treatment application. The main factors involved when selecting the proper SMARTVALVE system include the volume of water being treated in conjunction with the quality and flow (fixed or variable) of the water. Model 7007 may be used for chlorine or sulfur dioxide.

Regal Chlorinators 7007 is used for step rate control. This applies when multiple water lines with separate, fixed speed pumps (four maximum) lead to one main water supply. Based upon demand, the pumps will cycle on and off at various times and combinations, thus changing the overall water flow in incremental steps relative to the fixed flow rate of each pump.
