It features an epoxy-coated cast iron body, ductile iron poppet, 316 stainless-steel spring and stem, engineered composite cap and guide, a Nitrile (Buna-N) seal, and a galvanized steel strainer. It is rated for a maximum working pressure of 250 psi and a maximum temperature of 180°F (80°C).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMax Pressure: 250 psi\u003c\/p\u003e\n\u003cp\u003eMax Temperature: 180°F (80°C)\u003c\/p\u003e\n\u003cp\u003eBody: Epoxy-coated cast iron\u003c\/p\u003e\n\u003cp\u003eGuide: Engineered composite\u003c\/p\u003e\n\u003cp\u003ePoppet: Ductile iron\u003c\/p\u003e\n\u003cp\u003eSeal: Nitrile (Buna-N)\u003c\/p\u003e\n\u003cp\u003eSpring: Stainless-steel\u003c\/p\u003e\n\u003cp\u003eStrainer: Galvanized steel strainer\u003c\/p\u003e\n\u003cp\u003eConnection: 6\" FNPT threaded (ANSI B1.20.1)\u003c\/p\u003e\n\u003cp\u003eWeight: 55 lbs\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperation:\u003c\/strong\u003e The 63VFD Foot valve is mounted at the end of a suction pipe to help maintain pump prime and reduce reverse flow. The spring-assisted poppet begins to close as flow diminishes and closes fully as flow reverses, helping to limit backflow and hydraulic shock in systems with variable flow conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e An epoxy-coated cast iron body provides strength and corrosion protection, while the internal poppet, guide, and spring are selected by size to balance durability and hydraulic performance. The heavy-duty strainer offers a large open area to reduce head loss while helping to keep larger debris out of the suction piping. FNPT threaded ends simplify installation into standard threaded piping systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e Municipal, industrial, and commercial water systems using variable flow or VFD-controlled pumps where a robust, epoxy-coated cast iron foot valve with a galvanized strainer is required to help maintain prime and protect against backflow and debris.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e** Galvanized Strainer Only.\u003c\/em\u003e\u003c\/p\u003e","brand":"Flomatic","offers":[{"title":"Default Title","offer_id":46636593447075,"sku":"4789VFD","price":1071.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2058\/5123\/files\/Flomatic_63.png?v=1765481240","url":"https:\/\/dadepump.com\/products\/flomatic-63-6-cast-iron-vfd-foot-valve-galvanized-strainer-4789vfd","provider":"Dade Pump \u0026 Supply","version":"1.0","type":"link"}
