Introducing Flomatic’s Model 745 Surge-Stopper ®


Effectively Prevent Slamming
During Rapid Flow Reversal

Flomatic’s Model 745SC Surge-Stopper® is a precision-engineered swing check valve incorporating a rapid closure spring in conjunction with a resilient flapper hinge, resulting in reduced disc closing time.

As a result, it effectively prevents slamming during rapid flow reversal, which is commonly encountered in applications with high head, surge tanks, or multiple pumps.

Built to Last
Design to Perform

Designed with performance in mind Its 45-degree seating surface minimizes disc travel, typically 35° or less, and  rapid closure spring, helps prevent slamming during rapid flow reversals.

The resilient seating design boasts a one-piece molded flapper, comprising a reinforced flexible hinge and a steel flapper disc encapsulated in Buna-N rubber (EPDM optional). This design, along with the raised rib seal on the molded seating surface, ensures bubble-tight sealing even under low pressure and vacuum service.
