Series 700 ProFlex™ Rubber Check Valve
The Series 700 ProFlex™ Rubber Check Valves from Proco Products, Inc. are specifically designed for use in sewage treatment plants, outfalls, and tidal operations. They’re a cost-effective solution for controlling back pressures, and are a fully passive flow device, requiring no maintenance, no outside power sources or manual assistance to operate.
The Series 700 ProFlex™ rubber check valves are recommended as direct replacements for ineffective, maintenance-ridden flap type check valves, which are commonly known to seize, rust, or bind in unwanted positions. The Series 700 ProFlex™ rubber duckbill check valves provide backflow protection from occurrences including:
- Sewage slurries
- Outfalls to ocean fronts from heavy rainfall activity
- Land erosion due to back flow conditions
- Invasion of saltwater to freshwater pond
*All check valves have been fully tested at an accredited flow laboratory and flow charts are available upon request.
