Dosatron COMPLETE INJECTION STEM ASSY D8RE5VF -HV – Viton Seals

Precision Metering for 40 GPM High-Flow Systems The Dosatron D8RE5VF Injection Stem Assembly (Part #8CD034VF) is the essential metering component responsible for regulating the accurate intake of concentrates in high-flow environments. Engineered for the D8RE series—Dosatron’s industrial workhorse capable of handling water flows up to 40 gallons per minute (8 m³/h)—this assembly ensures that your solution is mixed at a constant 1% to 5% ratio regardless of variations in system pressure. As a complete "metering part" assembly, it allows for a comprehensive restoration of the injector's lower end, maintaining the factory-calibrated volumetric precision required for high-performance greenhouse and nursery management. Advanced Chemical Resistance and Durability This specific assembly is equipped with high-durability Viton (VF) seals, making it the primary choice for applications involving acidic additives, fertilizers, and most soluble cutting oils. The "High Volume" (HV) construction is built to withstand the mechanical stresses of continuous-duty fertigation, where consistent delivery of nutrients or plant protection products is critical to crop health. By replacing the entire injection stem assembly, facility managers can effectively eliminate suction leaks and ensure a pressure-tight interface for reliable 1:100 to 1:20 proportional dosing. Key features: Direct OEM Replacement: Specifically engineered for the Dosatron D8RE5VF series to ensure an exact factory fit and immediate restoration of dosing accuracy. Viton (VF) Seal Integration: Provides superior resistance to acidic chemicals and fertilizers, ensuring long-term seal integrity in demanding industrial environments. Precise 1% to 5% Injection Range: Supports a versatile range of application rates for everything from standard fertilizers to targeted pH correction. High-Flow Capability: Optimized for systems operating up to 40 GPM (8 m³/h), providing the robust performance needed for expansive greenhouse ranges. Complete Maintenance Solution: Simplifies the repair process by providing a pre-assembled metering unit, reducing facility downtime and maintenance complexity.
