Product characteristics The fluid resistance is small, and the sealing surface is brushed and eroded by medium. Opening and closing is more labor-saving. Medium flow direction is not limited, no disturbance, no reduction of pressure. The utility model has the advantages of simple structure, short structure length, good manufacturing technology, high temperature resistance and high pressure resistance, and many optional materials, and wide application range.
