What`s the Material of our Valve Seat ?
Here is the valve seat material we ever made for our customers ,you also can give your own material chemical composition or choose other material from our material list.
Cobalt balls are used in wear and high temperature applications, particularly where lubrication is marginal. We are capable of manufacturing cobalt balls in several alloys. There are many trade names used for different alloys and often cobalt balls are referred to as cobalt alloy balls Haynes balls, or Rexalloy balls. The different alloy compositions are used for applications in valves, ball and seat, regulators, bearings and ball screws in many industries including petroleum and nuclear.
API Standard Cobalt Alloy Valve Seats and Valve Balls:
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 contact.
