{"product_id":"dosatron-d128r-actuator-assembly","title":"Dosatron® D128R Actuator Assembly","description":"\u003ch3\u003eProduct Overview\u003c\/h3\u003e\u003cp\u003eA compromised actuator assembly in your Dosatron unit can bring your entire fertigation program to a grinding halt. When the drive mechanism fails, your crops lose access to critical nutrients or chemical treatments, leading to stunted growth, nutrient deficiencies, or total crop loss. This risk is amplified during peak growing seasons and late spring demands when your systems must run at full capacity to meet production schedules. Supply chains for specialized injection parts can be unpredictable, and relying on back-ordered components during a heatwave is a risk your business cannot afford. By stocking the D128R Actuator Assembly now, you ensure your injection systems remain operational, keeping your projects on schedule and your clients satisfied with consistent results.\u003c\/p\u003e\u003cp\u003eThe Dosatron D128R Actuator Assembly is engineered for superior chemical resistance compared to generic internal components, providing a tighter seal and more reliable stroke cycle. This authentic replacement part eliminates the guesswork of troubleshooting, saving your crews hours of diagnostic labor and reducing the long-term maintenance costs associated with system downtime. Using factory-spec parts ensures that your injection rates remain precise and consistent across the entire irrigation zone. Professionals who maintain a ready inventory of these high-wear components gain a significant competitive edge by providing immediate repairs that keep systems running while competitors are still waiting on parts deliveries.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-Grade Chemical Resistant Composite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eDosatron D128R Series Injectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eDrive Mechanism Actuation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Pressure\u003c\/td\u003e\n\u003ctd\u003eRefer to Injector Body Rating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\/Finish\u003c\/td\u003e\n\u003ctd\u003eFactory Standard Black\/White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eManufacturer Original Equipment Part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThis specific actuator assembly is designed for the Dosatron D128R series injectors.

Carefully remove the injector top and extract the old assembly, taking note of the orientation to ensure proper alignment of the new drive components. We recommend lubricating O-rings with a manufacturer-approved silicone lubricant to ensure a proper seal and prevent pinching during reassembly. Always follow local plumbing codes regarding backflow prevention when using chemical injection systems in potable water environments.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158386667809,"sku":"120660","price":41.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/120660_PR.png?v=1766410388","url":"https:\/\/asiwsupply.com\/products\/dosatron-d128r-actuator-assembly","provider":"ASIW","version":"1.0","type":"link"}
