XH81 type sewage rubber check valve

Duck billed valve and rubber check valve products are mainly 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.

Manufacturing materials for duckbill valves: chloroprene rubber, Haplon, nitrile rubber, and ethylene propylene rubber.

Installation method and size of duckbill valve: It is made of rubber flange, valve body, and duckbill, and is equipped with a padded metal flange. It can be naturally connected to the metal flange and directly installed on the tank, pipeline, and cofferdam. When installing the connection, the dimensions of the flange and the connecting flange should correspond. Waterproof glue should be added between the flange and the connecting flange according to the specific situation to ensure absolute sealing after the connection is tightened. It is also important to avoid damaging the flange lip of the duckbill valve.

Product Features

1. High-quality materials: The valve is made of EPDM rubber, which is resistant to corrosion, aging, and high temperatures.

2. Flanged connection: The valve is designed with a flanged connection, which makes it easy to install and replace.

3. Anti-backflow design: The duckbill-shaped valve body can effectively prevent the backflow of sewage, ensuring the smooth flow of the pipeline.

4. Long service life: The valve has a long service life and can be used for a long time without maintenance.

5. Easy maintenance: The valve is easy to maintain and clean, and can be replaced quickly in case of damage.

Product Applications

This duckbill check valve is widely used in sewage treatment plants, municipal drainage systems, and industrial wastewater treatment systems. It can be installed in pipelines to prevent the backflow of sewage and ensure the smooth flow of the pipeline.
