Precision Metering for D14 Series Fertigation Systems
The Dosatron Injection Stem Assembly (Part #CDDI074VF) is the essential suction and metering core for the D14MZ2, a high-performance injector capable of handling water flow rates up to 14 gallons per minute. This assembly is responsible for creating the volumetric vacuum required to draw concentrated additives into the mixing chamber at a consistent 0.2% to 2% (1:500 to 1:50) injection ratio. As a genuine OEM replacement, the CDDI074VF restores the factory-calibrated accuracy of your unit, ensuring that specialized nutrients or plant protection products are mixed uniformly into the water stream regardless of fluctuations in mainline pressure or flow speed.
Industrial Viton Resilience for Acidic Applications
This specific assembly is equipped with high-durability Viton (VF) seals, making it the primary choice for applications involving acidic fertilizers, pH-down solutions, and specialized industrial mineral oils. The "High Volume" (HV) construction is engineered to withstand the mechanical stresses of continuous-duty fertigation in professional cultivation environments. By replacing the entire injection stem assembly, facility managers can effectively eliminate suction leaks and ensure a pressure-tight interface, preventing air from entering the nutrient stream and maintaining the volumetric precision required for high-performance crop management. This complete unit simplifies maintenance by providing a pre-assembled solution for the injector's lower end.
