New Flomatic AIS & BABA Compliant 12' Flo-Flex 745SC Surge-Stopper For Municipal And Industrial Water Systems

Flomatic Valves is proud to announce the official release of its new AIS (American Iron and Steel) and BABA (Build America, Buy America) Compliant 12” Flo-Flex 745SC Surge-Stopper. Designed for municipal, industrial, and wastewater applications, this advanced swing check valve meets ANSI/AWWA Standard C508 full waterway design requirements.

Engineered for durability and reliability, the ductile iron body valve features a rapid-closure stainless-steel spring that minimizes flapper disc hinge closing time—preventing slamming during rapid flow reversals and water hammer. Its unique spring design is angled at a 45-degree seating surface, minimizing disc travel. A raised rib seal on the molded Buna-N flapper disc ensures bubble-tight sealing under low pressure, making it suitable for vacuum service.

The Flo-Flex 745SC Surge-Stopper supports horizontal or vertical (flow-up) pipeline installations and offers optional accessories for enhanced functionality:

Smart Maintenance
Maintenance is simple and efficient for the Flo-Flex 745SC Surge-Stopper.
