DLSEASL Rubber Check Valve Silicone One Way Small Mini Duckbill Valve one way flow control silicon duckbill valves

Duckbill check valve introduction The shape of this product is similar to duckbill, so it is called duckbill valve. Duckbill valve is also known as check valve, one-way check valve, back pressure flexible check valve, rubber check valve, rubber slow closing, check valve, etc. Working principle of duckbill valve: When the appropriate pressure liquid or gas passes through the valve, the duckbill outlet opens the valve under the action of its own elasticity; as the internal flow pressure or pressure increases, the opening range of the duckbill valve also increases to keep the liquid in Discharge at high flow rate. When the water flow stops, the backwater pressure or atmospheric pressure will tighten the duckbill valve to prevent the backflow of liquid or gas. Our company uses all-rubber structure, corrosion resistance, long service life and good effect. And provide a tight seal to prevent backflow, backflow, and maintenance-free. When installing a check valve, pay special attention to the flow direction of the medium. The normal flow direction of the medium should be consistent with the arrow direction indicated on the valve body, otherwise the normal flow of the medium will be blocked.
