The new Model 80EVFD \u0026amp; 100EVFD, like the Model 80DI\/SS VFD, are designed to minimize flow loss and hydraulic shocks in the pumping system. The standard unleaded bronze body or optional Stainless Steel or epoxy coated (NSF approved powder) ductile iron body are designed to support submersible pumps set deep in a well-water casing. Its unique hydraulic custom molded Buna-N rubber sealing surfaces are supported by a mechanical back-up support to maximize the check valve service life. The patented spring loaded poppet system is guided in a generous seat bore. The unique patented poppet system (all Stainless Steel in larger sizes and optional in the smaller sizes) insures that the valve is noiseless during operation and automatically closes tight after each pump cycle. The tapered seat allows a self-cleaning “one point swiping action” by the radius-edged rubber seal during each valve closing cycle. All internal parts are made from corrosion resistant material.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNSF\/ANSI 61 approved\u003c\/li\u003e\n\u003cli\u003eLow head loss\u003c\/li\u003e\n\u003cli\u003eReduces hydraulic shock\u003c\/li\u003e\n\u003cli\u003eCorrosion resistant internals\u003c\/li\u003e\n\u003cli\u003eCustom-molded Nitrile (Buna-N) seal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWell water pump systems\u003c\/li\u003e\n\u003cli\u003eWater applications\u003c\/li\u003e\n\u003cli\u003eIrrigation systems\u003c\/li\u003e\n\u003cli\u003eSprinkler systems\u003c\/li\u003e\n\u003cli\u003eGasoline\/Oil applications\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Flomatic","offers":[{"title":"Default Title","offer_id":45717802516643,"sku":"4033EVFD","price":117.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2058\/5123\/files\/80100EVFD.jpg?v=1742753656","url":"https:\/\/dadepump.com\/products\/flomatic-4033evfd-1-1-2-80evfd-enviro-check-r-unleaded-bronze-check-valve-composite-internals","provider":"Dade Pump \u0026 Supply","version":"1.0","type":"link"}
