Duckbill Check Valve

Duckbill Check Valve, also known as Duckbill Valve, Duckbill Non Return Valve and One Way Duckbill Valve. Duckbill Valve is elastomeric component that act as backfolw prevention devices or one-way valves or check vlaves. Duckbill Valves have elastomeric lips in the shape of a duckbill which prevent backflow and allow forward flow. A range of materials and designs are available to handle different fluids and services conditions.

Duckbill Check Valve Applications：

• Wastewater treatment plants;

• Swer System;

• Portable water holding tanks, single in/ single out only;

• Pump protection( water hammer/ vlave slam);

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

• Stormwater Discharge;

• Flood Control Prevention;

• Effluent Diffusers;

• Retrofit System;

• Mining Outfall and Tailing Pond Overflow Pipe.

Duckbill Check Valve Advantages:

• Precise fluid flow control

  The duckbill valve opens and closes according to the direction of the fluid flow and can be used to regulate the flow rate of the fluid. This makes duckbill valves ideal for applications that require precise control of fluid flow, such as food and beverage production and the pharmaceutical industry.

• Excellent Sealing Properties & Leak Proof Performance

  The duckbill valve only allows the fluid to flow in one direction, which can effectively prevent leakage and backflow. This makes it ideal for applications where leaks are not allowed, such as medical devices and water treatment systems.

• Easy to  Install and Require Minimal Maintenance

  Duckbill valves are easy to install and require no special tools or equipment. Due to its flexibility and durability, very little maintenance is required.

• Cost-Effective

  Duckbill valves are cost-effective compared to other types of valves, making them ideal for large-scale applications.

• Highly Versatile

  Duckbill valves are available in a variety of materials and sizes, making them suitable for a wide range of fluids and operating conditions. They can be used in both low and high pressure applications and can withstand extreme temperatures and harsh chemicals.

Duckbill Check Valve's Materials:

Duckbill Check Valve is mainly made from elastomer rubber like silicone, fluorosilicone & FVMQ, EPDM, HNBR, Buna N & Nitrile Rubber, Neoprene at lower hardness and compression set.

• FDA food grade & medical grade Umbrella Valve can be reused, comply with Food and Drug Administration Regulations, and can work at -40℃ to 230℃, at elevated temperatures, the tensile, elogation, and abrasion resistance far superior to that of most organic elastomers. Low temperature flexibility is a major advantage silicone over most organic rubbers.

• LSR & Liquid Silicone Rubber Umbrella Valve: Unlike conventional rubber, LSR can withstand extreme temperatures without changing its properties, can be automatically sterilized at high temperatures or used in very cold environments.

• Fluorosilicone & FVMQ Umbrella Valve have good oil resistance, strong acid resistance, alkali resistance, antioxidant performance, and has common silicone advantage like working temperature of -40℃ to 230℃.

• EPDM Umbrella Valve have excellent performance at Ozone aging resistance, weather aging resistance and heat resistance.

• Buna N & Nitrile Rubber Umbrella Valve performs excellently at oil resistance.
