Feature

Besides the functions of general check valve, axial flow check valve can realize zero leakage with its double-sealed seat. There are advantages of small fluid resistance, small water pressure, good flow pattern, quick response to pressure changes, and small overall dimensions thanks to unique design of Venturi streamlines. It’s the optimum choice for oil-gas transportation pipeline network system home and abroad, especially for oil pumps.
