The pump discharge check valve is an essential element in the design of water and wastewater pumping systems. The valves work to protect valuable pump equipment, automatically opening to allow for forward flow and automatically returning to the closed position to prevent reverse flow when the pump is not in operation. The Flo-Flex Model 745 rubber disc swing check valve from Flomatic Valves provides the water and wastewater industry one of the broadest lines of flexible rubber disc swing checks available on the market today.

Constructed for industrial and municipal applications, these check valves include a strong ductile iron body coated (internally and externally) with a fusion-bonded epoxy coating, a fast-paced 45-degree valve-seat angle for short disc travel distance, and non-slam high performance resulting in the reduction of water hammer. It is also available in an AIS-compliant model.

“We felt it was extremely important to add an AIS-compliant check valve to our 745-swing check model line,” says ­­­­­Jim Tucci, national sales manager at Flomatic Valves. “It includes all the same features as our traditional Model 745 with additional benefits such as a raised body boss, which is drilled, tapped and plugged for easy installation of gauges or accessories.”

Manufactured according to ANSI/AWWA C508-01 standards, the Model 745 provides the industry a broad lines of flexible rubber disc swing checks featuring a maximum temperature of 140 degrees F, pressure max of 250 psi, vertical or horizontal installation, stainless steel hardware, a standard drain plug, a Buna-N coated disc rubber seal, low headloss for a smooth operation, and ease of accessibility for installation and serviceability. It is available in a size range of 3 to 12 inches, providing the water and wastewater industry with one of the broadest lines of flexible rubber disc swing checks available on the market today, according to Tucci.

“The valve’s short disc travel allows for faster closure. Its valve body flow area is equal to nominal pipe area,” says Tucci. “It offers easy in-line serviceability, and it can be installed for vertical flow or in a horizontal direction. Its precision molded valve disc is a one-piece construction, with integral O-ring type sealing.”
