Dilution Solutions 1 1/2 in Check Valve

1-1/2 Inch Check Valve for Dosatron Injectors – CV112

The Dilution Solutions CV112 is a 1-1/2 inch check valve designed for use with Dosatron proportional injectors that have viton seal assemblies and a 1-1/2 inch connection. Check valves allow fluid to flow in one direction only — in a nutrient injection system, the check valve prevents the flow from reversing direction, which could cause concentrated nutrient solution to backflow into the supply water line.

The CV112 is constructed from polypropylene for resistance to the acids, salts, and other chemicals used in hydroponic nutrient solutions. It installs at the 1-1/2 inch connection point on the compatible Dosatron unit.

Key Features & Benefits

• 1-1/2 Inch Connection — Sized for Dosatron injector units with a 1-1/2-inch connection.
• Viton Seal Compatibility — Designed for use with Dosatron units that have viton seal assemblies.
• Poly Construction — Polypropylene construction for chemical resistance to nutrient solution components.
• Prevents Backflow — Allows flow in one direction only — prevents concentrated solution from entering the supply line.
• Direct Dosatron Integration — Installs directly at the Dosatron's outlet connection point.
• Chemical Resistant — Resists the acids, salts, and mineral compounds in hydroponic nutrient solutions.

Who Should Use This Check Valve

The CV112 is for growers using Dosatron proportional injectors in irrigation and fertigation systems. Install the CV112 at the outlet of compatible Dosatron viton seal units to prevent nutrient solution backflow into the supply line, which protects the upstream supply from contamination.

Why Check Valves Are Used in Dosatron Injection Systems

Dosatron proportional injectors draw nutrient concentrate from a separate container and inject it into the water stream at a fixed ratio based on water flow. If water pressure in the system drops or the pump stops, there is a risk of backflow — the nutrient-laden water downstream could flow backward through the injector and into the upstream supply line, contaminating it with concentrated nutrients. A check valve installed at the outlet of the injector prevents this backflow by mechanically blocking reverse flow regardless of pressure conditions.

Frequently Asked Questions

What Dosatron units is the CV112 compatible with?

The CV112 is designed for Dosatron injectors with viton seal assemblies requiring a 1-1/2 inch connection.

What is a check valve?

A check valve allows fluid to flow in one direction only. It blocks reverse flow to prevent backflow from the injection system into the supply water line.

What material is the CV112 made from?

The CV112 is constructed from polypropylene for chemical resistance.

Where is it installed?

The CV112 installs at the outlet connection of the Dosatron unit.
