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.

Features:

• Automatic switch according to water pressure difference, safe and reliable
• The forward opening water resistance is small, the starting pressure is small, and it is automatically adjusted according to the water pressure.
• Reverse sealing is good
• Anti-corrosion, aging resistance, no deformation, strong adaptability
• Wide size range, nominal diameter DN50-DN3000
