2 Inch Cobalt Alloy Stellite 20 Valve Ball EB9109

Cobalt 6 Inch Valve Ball EB9109

We produce high temperature Superalloy Cobalt Valve Balls and Valve Seats with high precision.

Cobalt alloy valve balls and seats are produced with cast and metallurgic powder process.

Stellite21 high wear Co balls and seats are used for oil and gas industries.

We melt good quality Co-based Alloy Castings with Vacuum Furnaces and Induction Furnaces.
We can cast and machine the hard Cobalt-based Alloy Castings as per the drawings.
We would like to help select suitable Co-based Alloy Grade as per your specific working condition.

Cobalt-based alloys have been in use for producing various components such as vanes or combustion chambers. The material can be implemented as wrought or as precision-cast parts or as centrifugal cast parts. The design of cobalt superalloys, which is aimed at an enhancement of both their oxidation resistance and their hot corrosion resistance, has received considerable impetus recently, especially since the advent of overlay coating techniques and the extensive studies which have been undertaken to elucidate the hot corrosion mechanisms and the effect of alloying elements.

Application and Advantage:

1. Valve balls and valve seats  are widely used  in oil fields.

2. Valve Ball and Seat performance directly affects the use effect and service life of the sucker rod pumps.

3. Each ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of connection.
