The JOEPAI 2PC Carbon Steel Flanged Ball Valve adopts a compact structure and a floating core design. The sealing surface between the ball and the valve seat automatically seals under pressure, and with a sturdy carbon steel valve body, it has good data in pressure bearing, wear resistance, corrosion resistance, etc. It is widely used in industries such as petroleum, natural gas, chemical, power station, and water treatment. With over ten years of experience in ball valve manufacturing, Qiaopai adopts CNC precision machining, five quality inspection checkpoints, and a digital process tracking system to achieve factory traceability, stable performance, and precise matching with customer standards for each ball valve. Multiple standards such as DIN, ANSI, JIS, etc. are available to meet the customized procurement needs of global customers.
