Sytop Stellite Alloy 3

Stellite Alloy 3 Valve Seat are very important parts of underground oil-well pump , they always show up together and cooperate very good , no better material can replace Stellite Alloy now .

The valve balls are made of Stellite Alloy 20 and Stellite Alloy 3 Valve Seatare made of Stellite Alloy 3 . They are a good team to resist the wear and corrosion issue in oil and gas pimping process .
