Mister Mist'r

Stainless steel Mister Mist’rs are great for high-volume applications.

To back our position as a leader in fluid injection technology, Agri-Inject developed the most advanced injection check valve available on the market today. Efficient, consistent fluid injection is essential – and our Mister Mist’rTM (U.S. Patent No. 6,230,982) valves deliver where it counts.

Mister Mist’r also serves as a positive two-way check valve to prevent backflow of water into the system. This also prevents accidental leakage of chemical into the mainline water stream during shutdown. Mister Mist’r has been approved as a chemigation check valve by all state and federal regulatory agencies, so you are assured that your Agri-Inject system is in compliance no matter where you are!

Taken during Colorado State University testing, these pictures show Mister Mist’r (top) completely distributing nutrients compared to a conventional valve (bottom).

As shown in the image on the right, the four-way spray design essentially atomizes the injected product and evenly distributes it into the irrigation water flow, compared to our competitor’s check valves.

In addition, moving parts are continually cleaned by moving water, ensuring a long life.

Agri-Inject plastic models are suitable for use in 6-12 inch diameter pipe and can handle volumes of up to 110 gallons per hour.

Stainless steel models are designed for high-volume applications of up to 300 gallons per hour. They are also available for use in a wide range of pipe diameters.
