Product Introduction

Rubber Flex Duckbill Check Valves, also known as back pressure flexible check valves, duckbill check valves, or rubber check valves, are valves used to regulate pressure in pipelines such as fire protection systems, gas systems, and air conditioning systems, ensuring stable pressure in the pipeline. The duckbill valve has a duckbill shaped valve, which controls the pressure of the pipeline by adjusting the valve’s switch. When the pressure in the pipeline exceeds the set range, the duckbill valve will automatically close to protect the safety of the pipeline.

Rubber Flex Duckbill Check Valves can prevent floods and sewage from flowing back into street sewers and basements, avoiding significant losses, and preventing floods from flowing back into sewage treatment plants and drainage pumping stations when water levels rise; Prevent the spread of odor from sewage or odorous fluids, and allow for drainage at any time; In rainy seasons, it can prevent urban river floods from flowing back into the streets; The quality is better than the shutter, overcoming some defects such as loose closing of the shutter.

Rubber Flex Duckbill Check Valves are specially processed from elastic chloroprene rubber and synthetic fibers, with a shape similar to a duckbill, hence the name duckbill valves. Under no internal pressure, the duckbill outlet closes under its own elastic action; As the internal pressure gradually increases, the outlet of the duckbill gradually increases, maintaining the liquid to be discharged at high flow rates.

The main purpose of the flange type rubber drain check valve product is to be used in waterproof systems, discharge systems, water pump outlets, lifting pump stations, and underwater aeration systems Main features of the product: The rubber flange is integrated with the valve body, making installation extremely convenient. The valve body adopts an all rubber design, which will not cause sedimentation or blockage, reducing maintenance costs and allowing solid particles to pass smoothly. Valve body manufacturing materials: chloroprene rubber, ethylene propylene rubber, nitrile rubber, and ethylene propylene rubber, etc; Material of flange: Q235304316, etc.

The clamp type duckbill valve is widely used in coastal areas, beaches, docks, reservoirs, municipal flood discharge, and sewage discharge. It can be said to be an environmentally friendly and green valve. This valve replaces the clapper gate check valve, completely solving the problem of clapper gates being easily blocked by mud, silt, stones, vegetation, and marine organisms. Clamp type duckbill valve products are mainly used in waterproof systems, discharge systems, water pump outlets, lifting pump stations, and underwater aeration systems.

Advantage

1. 100% all rubber structure, can meet various anti-corrosion requirements (different rubber materials can be selected according to actual needs).

2. Not clogged, well sealed.

3. Long service life, no faults, and maintenance free.

4. There are no moving or mechanical components, no electrical signals or manual operations required, and no noise.

5. The opening pressure is small, and a water head greater than 0.01 meters can be opened.

6. Under normal conditions, the head loss can be reduced to a very small extent.

7. Can change various installation forms to meet customer needs.

8. Convenient installation, low cost, and low operating cost.
