Description

APCO CRF-100C/100 Rubber Flapper Swing Check Valves are uniquely simple in design but durable for use on a variety of applications. The valves are engineered and tested to meet the requirements of the AWWA C508 standard. Standard construction includes an internal leaf spring to assist in closure prior to flow reversal. Available in sizes 2-48″ (50-1200mm), they are available in ductile iron bodies with ASME 125/150 flanges. For additional abrasion resistance, 100% flow area bodies can be lined with elastomers.

Since the APCO CRF Rubber Flapper Swing Check Valve was introduced in 1965, it has been operating successfully in thousands of installations. The features of the Rubber Flapper Swing Check Valve make it ideally suited for applications such as raw sewage, water systems, industrial wastes, chemical lines, erosive services, ash service, acid lines, tailings systems, light slurries, corrosive services, leaching lines, scrubbers, brine and salt water systems.
