This model is intended for demanding pumping applications and includes spring-assisted closure (Surge-Stopper®) to help reduce reverse flow and mitigate water hammer in high-head, long pipeline systems. Construction includes an epoxy-coated ductile iron body and cover with a Buna-N coated Flo-Flex® disc, and corrosion-resistant hardware for long service life. It is rated for a maximum working pressure of 250 PSI and a maximum temperature of 140°F (60°C).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eStandard: AWWA C508\u003c\/p\u003e\u003cp\u003eBody \u0026amp; Cover: Epoxy-coated ductile iron\u003c\/p\u003e\u003cp\u003eDisc: Flo-Flex® 45° seat, Buna-N coated\u003c\/p\u003e\u003cp\u003eMax Pressure: 250 PSI\u003c\/p\u003e\u003cp\u003eMax Temperature: 140°F (60°C)\u003c\/p\u003e\u003cp\u003eFlange Rating: ASME Class 150\u003c\/p\u003e\u003cp\u003eConnection: 3\" Flanged, ASME 150#\u003c\/p\u003e\u003cp\u003eWeight: 40 lbs\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOperation:\u003c\/strong\u003e During forward flow, the disc opens to allow full flow through the valve. As flow decelerates and reverses, the Flo-Flex® disc closes smoothly on the 45° seat to reduce slam and hydraulic shock. The Surge-Stopper® spring-assisted mechanism is designed to accelerate closure in long pipeline systems to help reduce pressure surges. The external position indicator provides a visual reference of disc position for operational checks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e Heavy-duty epoxy-coated ductile iron construction with a Buna-N coated Flo-Flex® disc supports reliable sealing and long service life.
