Fleyenda Wafer Silent Check Valve prevents backflow and water hammer by automatically closing the disc at zero flow. The disc is fully guided to avoid jamming or tilting and opens at pressures below 0.5 psi. Standard configuration includes a fusion-bonded epoxy-coated ductile iron body, a stainless steel disc, and a rubber seat, ideal for applications requiring low cost and shock-free operation. Available options include wafer silent check valves in cast iron, carbon steel, stainless steel, and special alloy castings, with ample stock for immediate shipment.
