Rubber Duckbill Check Valve

Rubber Check Valves are specifically designed for use in sewage treatment plants, outfalls, and tidal operations. They’rea cost-effective solutions for controlling back pressures and are fully passive flow devices, requiring no maintenance, no outside power sources, or manual assistance to operate.

RubberCheck 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. Rubber duckbill check valves provide backflow protection from occurrences including:

- Sewage slurries

- Outfalls to ocean fronts from heavy rainfall activity

- Land erosion due to backflow conditions

- Invasion of salt water to a freshwater pond

Applications Include:

• Wastewater treatment plants

• Sewer systems

• Potable water holding tank, single in/single out only (including tank overflow pipes)

• Pump protection (water hammer/valve slam)

• Airport runways, parking lots, residential areas, commercial centers

• Stormwater Discharge

• Flood Control Prevention
