Cemented Carbide Balls, Valve Seats, and Valve Cores for Oil and Gas Industry
All our balls, valve seats, and valve cores meet API standards.
For balls, we offer 5/32″ to 2 1/2″ diameter in grades 10, 25, 50, 100, 200
Our valve seats are finished in the port area and undergo rigorous pressure testing. Primarily employed in various valves such as throttle valves, gate valves, check valves, cock valves, needle valves, and choke valves, our cemented carbide valve cores and valve seats serve versatile applications. Customized to your specific technical drawings and material specifications, we create a wide range of seats and cores. Please note that we do not offer standard valve seats and cores; each product is tailored to meet individual requirements.
