Metal seated valve ball and seat is the critical parts of metal seated ball valves. It is designed for extreme high pressure, temperature and abrasive conditions, such as cutting off or connecting solid granules, melted slurry,coal power, scalding cinder, steam water or other liquid etc.
For metal seated ball and seat, we must provide complete valve ball+seat kits solution to customers because the ball and seat need lapping before being sent to serve. Over the years, we have developed a unique ball lapping technology for the coated ball and seat. Through simultaneous same the different direction of rotation, the ball and the seat result in perfect.
