Product Description


Customized Backflow Prevention Silicone One Way Floor Drain Duckbill Check Valves for Kitchen Sewer

Introduction of duckbill valve;


First, the main use of duckbill valve

Duckbill valve is widely used in coastal, beach, wharf, reservoir, municipal flood discharge and sewage discharge. It can be described as an environmentally-friendly green valve, which replaces the check valve of flapper door and thoroughly solves the problem that flapper door is easily blocked by silt, mud, rocks, vegetation and marine life. Duckbill valve products are mainly used in waterproof system, drainage system, water pump outlet, lifting pump station and submerged aeration system.

Second, the working principle of duckbill valve
One Way Check Valve


Silicone Valves
Silicone Valves, also known as One Way Valves, Non-return Valves, Air Flow Valves, Rubber Check Valves, which are used for controlling the direction of air or fluids' flow. Our silicone valves can be universally applied in many different applications, whether in the health care, automotive, appliance or food and packaging industries. Silicone valves include umbrella valves, duckbill valves, membrane valves, flapper valves and diaphragm valves, etc.



Silicone Rubber Umbrella/Duckbill/Check/Flapper/Die-cutting Valves

Silicone Rubber Check Valves, are also called one way valves, non-return valves, air flow valve, which are one popular type of silicone rubber one way valve, used in air control device or liquid & water flow controllers like medical tubing or pip air pressure controllers device, diving equipment, toilet products, outlet valves, automotive fuel tanks etc.

Umbrella Valves
Silicone Umbrella Valves, known as Mushroom Valves or Umbrella Check Valves. Rubber Umbrella Valves have round diaphragm seals & seat for air or water pressure relief and backflow controls. The stem and hooks of umbrella valve is for fixing. Umbrella valves are generally made from medical grade or food garde silicone or LSR materials. Other rubber materials like EPDM, NBR etc. are available in our company.




Duckbill Valves
Duckbill Vallve, as a elastomeric fluid-flow control components, seals or nozzles, is one type of rubber one way valves. The duckbill design aim to automatically prevent air or fluid backflow and allow forward flow.

Duckbill valve is made of elastic chloroprene rubber and artificial fiber by special processing, and its shape is similar to duckbill, so it is called duckbill valve, which is an all-rubber structure. Under the condition of no internal pressure, the duckbill outlet closes under the elastic action of itself; With the gradual increase of internal pressure, the duckbill outlet gradually increases, keeping the liquid discharged at high flow rate, preventing backflow and backflow. Small-diameter duckbill valves need to focus on how to reduce resistance and head loss, while large-diameter duckbill valves need to consider how to prevent reverse backwater.
