TwinFlo SXT

Summary

Product identification

• Product Name: TwinFloSXT
• Type: Residential Twin Tank Control Valve
• Part Number: 42804 Rev B

Features

• Uses 100% capacity of the tank in service before switching to the second tank, saving salt and water.
• Rinses away hardness reversion and stagnant water before the stand-by tank comes on line.
• Regenerates with soft water, keeping the system clean for optimum operating efficiency and minimum maintenance.
• Regenerates immediately when needed for continuous soft water 24 hours a day.
• Valve delivers continuous soft water.
• Meter-initiated regeneration.
• Super capacitor for keeping time during a power outage.

Options

• Fiber-reinforced polymer or stainless steel bypass valves.
