Dosatron proportioner venturi valve, used to properly mix drinking line cleaning solutions and other chemicals at adjustable rates.
Dosatron proportioner venturi valve is an economical means of accurately dispensing chemicals under constant pressure and flow conditions.
Dosatron’s 3/4” MGHT, self-cleaning polypropylene proportioner is chemical resistant and includes a built-in check valve designed to prevent back filling into the concentrate tank. The 2 GPM proportioner operates from 7 psi to 58 psi and it handles hot water up to 160º F.
A simple 1/4 turn of the handle changes the function from dosing (ON) to rinsing and a system of 12 color coded tips are provided for various injection rates. Back flush mode allows for easy cleaning.
Venturi proportioners, under constant pressure and flow conditions, provide an economical means of accurately dispensing chemicals. This simple device offers a wide array of injection rates and performs at high temperatures.
- Flow rates up to 2 GPM at 58 psi in ON mode
- Flow rates up to 13 GPM at 58 psi in rinse mode
- Injection rate - 1:100 (1%) to 1:2.3 (43,6%)
- Maximum temperature 160º F
- Built-in check valve
- Suction valve and strainer
- Maximum vertical height from concentrate tank: 6'

| Yellow | 3.5% @ 7 PSI to 2.1% @ 58 PSI |
| Brown | 6.0 % @ 7 PSI to 3.6% @ 58 PSI |
| Dark Green | 7.7% @ 7 PSI to 4.5% @ 58 PSI |
| White | 10.4% @ 7 PSI to 6.6% @ 58 PSI |
| Blue | 15.3% @ 7 PSI to 10.6% @ 58 PSI |
| Purple | 21.2% @ 7 PSI to 15.5% @ 58 PSI |
| Grey | 32.8% @ 7 PSI to 22.4% @ 58 PSI |
| Tan | 34.8% @ 7 PSI to 23.0% @ 58 PSI |
| No Tip | 37.0% @ 7 PSI to 26.0% @ 58 PSI |
NOTE: These results were obtained injecting water. Product viscosity will change these rates.
- The higher the viscosity, the lower the injection rate
- The higher the pressure, the lower the injection rate
- Constant pressure and flow conditions are required to obtain repeatability (constant injection results over time)
