Dosatron® D128R Slide Valve Pin
Product Overview
A damaged or worn slide valve pin in your Dosatron unit can lead to immediate system downtime, resulting in uneven nutrient distribution or complete fertigation failure. During the peak of the growing season, a non-functioning injector causes critical delays that can lead to crop loss or stunted plant growth. Supply chain fluctuations often make small, essential parts difficult to source when you need them most. By securing these pins now, you avoid the risk of back-orders during high-demand windows and ensure your clients’ irrigation schedules remain uninterrupted.
Constructed from high-grade materials designed specifically for chemical resistance, the Dosatron D128R Slide Valve Pin offers superior longevity compared to generic or improvised hardware. This genuine replacement part ensures the internal timing of your injector remains precise, reducing the labor costs associated with troubleshooting erratic flow patterns or pressure drops. Maintaining a stock of these specialized pins provides your crew with a competitive advantage, allowing for immediate on-site repairs and reducing the overhead of secondary service calls.

Installation Notes
Before installing the D128R Slide Valve Pin, ensure the water supply is shut off and the internal pressure of the Dosatron unit has been fully bled. Use a clean, lint-free cloth to remove any debris from the valve housing before inserting the new pin. Follow the manufacturer torque and alignment specifications found in the D128 series manual to ensure the slide valve moves freely before reassembling the outer casing.
