Product Description
Product Overview
The EPDM rubber duckbill check valve is a flexible, maintenance-free check valve designed for reliable flow control in demanding industrial applications. Constructed from high-quality EPDM rubber and reinforced with synthetic fibers, this valve features a unique duckbill design that opens under pressure and closes automatically when flow stops.
Operating Principle
This valve operates on a simple yet effective principle: fluid flow opens the duckbill-shaped outlet, while backpressure or atmospheric pressure seals it shut when flow ceases. The valve requires minimal opening pressure (as low as 250 Pa) and contains no moving parts, ensuring long-term reliability.
Key Applications
- Water conservancy projects: Sluice gates, ship locks, and drainage culverts
- Wastewater treatment plants: Inlet and outlet protection
- Municipal drainage systems: Stormwater and flood management
- Agricultural irrigation: Flow direction and volume control
- Marine applications: Ship hold drainage and ventilation
- Coastal infrastructure: Sediment and silt prevention
