The Flo-Flex Model 345 is an AIS compliant foot valve flapper style swing check valve designed to meet the needs of demanding industrial, municipal, and centrifugal pumping applications.
Available in 3 to 12 in. (80 to 300 mm) sizes, this model is designed according to ANSI/AWWA C508 standards and is constructed in a corrosion-resistant, fusion-bonded, epoxy-coated ductile iron body featuring a 316 stainless steel strainer and class ANSI 150 flange connections. Its screen open flow area is over three times the open area of the nominal area pipe size while the one-piece molded disc allows 100% full flow in the open position.
This model features a number of reliable functions including a fast-paced 45-deg. valve-seat angle for short disc travel, non-slam high performance resulting in the reduction of water hammer, optional drilled/tapped/plugged raised boss for easy installation of gauges or accessories, and a low head loss design. It is specifically designed to seal securely and tightly to minimize pump suction losses.
