Dilution Solutions 3/4 In Check Valve

3/4 Inch Check Valve for Dosatron Viton Seal Injectors – CV34-PH

The Dilution Solutions CV34-PH is a 3/4 inch check valve for use with Dosatron proportional injectors that have viton seal assemblies and a 3/4-inch connection. Check valves allow fluid to flow in one direction only — in a nutrient injection system, this prevents concentrated nutrient solution from backflowing into the supply water line when pressure conditions change.

The CV34-PH is constructed from polypropylene for resistance to the acids, salts, and other chemicals used in hydroponic nutrient solutions. It installs on the 3/4-inch connection of the compatible Dosatron unit. The viton seal specification determines which check valve is compatible — confirm the seal type of the installed Dosatron unit before ordering.

Key Features & Benefits

• 3/4-Inch Connection — Sized for Dosatron injector units with a 3/4-inch connection.
• Viton Seal Compatible — Designed for Dosatron units with viton seal assemblies.
• Poly Construction — Polypropylene body for chemical resistance to nutrient solution components.
• Prevents Backflow — One-directional flow — blocks reverse flow from the injection side to the supply line.
• Outlet Side Installation — Installs at the outlet connection of the Dosatron unit.
• Chemical Resistant — Resists acids, salts, and mineral compounds common in hydroponic fertigation systems.

Who Should Use This Check Valve

The CV34-PH is for growers using Dosatron viton seal proportional injectors with 3/4-inch connections in irrigation and fertigation systems. Install at the outlet of the Dosatron unit to prevent concentrated nutrient solution from flowing backward into the supply line — protecting the upstream supply from contamination.

Why Dosatron Installations Require Check Valves

Dosatron proportional injectors draw nutrient concentrate from a container and blend it into the water stream at a fixed ratio based on water flow rate. If upstream pressure drops or the water supply pump stops, the pressure differential can cause the nutrient-laden water downstream of the injector to flow backward through the injector and into the supply line. A check valve at the outlet of the injector blocks this reverse flow regardless of pressure conditions, preventing nutrient contamination of the supply line.

Frequently Asked Questions

What Dosatron units is the CV34-PH compatible with?

The CV34-PH is for Dosatron injectors with viton seal assemblies requiring a 3/4-inch connection.

What is a check valve?

A check valve allows fluid to flow in one direction only. It mechanically blocks reverse flow when pressure conditions would otherwise cause backflow.

What material is it made from?

The CV34-PH is polypropylene construction for chemical resistance.

Where does it install?

The CV34-PH installs at the outlet-side connection of the Dosatron unit.
