Backflow-Resistant Rubber Check Valves

Sept. 7, 2022
The latest series in the Proco Products Proflex™ check valve product line can allow for full flow, yet closes quickly to prevent backflow.

Proco Products Inc. is a worldwide supplier of expansion joints and Rubber Duckbill check valves. Its latest contribution to the industry is the Series 700 ProFlex™ check valve product line. These valves are commonly used in the water and sewage industry. Rubber check valves are a cost-effective way to control back pressures from sewage treatment plants, outfalls, and tidal operations.

ProFlex™ check valves are designed to be a “zero maintenance” valve. The simple design allows effluent to force the two opposing rubber lips apart, permitting flow, yet quickly closing to prevent the return of tailings or slurries. All Proco check valves are manufactured completely of barnacle-resistant rubber with a top-quality fungicide.

Proco aims to accommodate as many industry standards as possible. For example, one of the most recent certifications acquired is NSF/ANSI 61 Standard certification on its Rubber EPDM Expansion Joints and ProFlex™ Rubber Check Valve product line. WW

Proco Products is exhibiting at WEFTEC22, booth 3529. To learn more, visit www.procoproducts.com.
