Product Description:
Duckbill Check Valve is a new type of water supply and drainage valve product with a duckbill shape and "forward flow, reverse check" function. It is made by analyzing the force and calculating the force according to different working conditions, using different design structures and selecting different rubber formulas for different working conditions. It is made by following special processes. When working in the forward direction, water flows into the inlet, and the valve can be opened with a small water pressure. The higher the water pressure, the larger the valve opening, and the faster the water flow. When working in the reverse direction, the valve end automatically closes and seals in the reverse direction. The higher the back pressure, the tighter the valve opening, and the better the sealing effect. It is widely used in municipal, water conservancy, and wastewater treatment projects to prevent backflow and reverse flow and is an ideal replacement for fan gates.
Performance:
Sealing performance: The rubber duckbill valve has excellent sealing performance, which can prevent liquid or odor from flowing back and effectively block the backward propagation of sound downstream of the pipeline.
Pressure resistance performance: Its valve body is particularly flexible, ensuring maximum pressure resistance while minimizing hydraulic loss, achieving a perfect combination of discharge and pressure resistance.
Automatic cleaning function: The special flow channel design inside the valve body ensures that the valve has automatic cleaning function, without sediment and sludge deposition.
Antifreeze performance: The valve body has good flexibility and elastic deformation, therefore it has good antifreeze performance.
