China Ball Valve Supplier - Ball Valve Manufacturer & Wholesale Supplier

Explore a variety of Chinese ball valves at Zhuhai Kunjian Technology Co., Ltd. As a leading manufacturer of cryogenic ball valves, we offer a range of types for different applications. Industrial users look for efficient valves that can provide reliable flow control. We supply bulk ball valves in large volumes to meet diverse industry needs. Procure bulk ball valves directly from us for more efficient, better outcomes. We offer a variety of options that allow industries to install compatible valves. This compatibility makes our valves more suitable for whichever application you choose.

Trunnion Mounted and Floating Ball Valves for Every Application

Our trunnion-mounted ball valves handle high-pressure, large-diameter pipelines where the ball needs extra support against flow thrust, making them a standard choice for oil, gas, and petrochemical lines. Floating ball valves work well for lower-pressure, smaller-bore applications where the seat itself holds the ball in place. We stock both in a range of sizes and pressure classes, so buyers can match the valve type to their line conditions instead of over-specifying for the application.

Cryogenic Ball Valves, Material Options, and API 6D Compliance

For ultra-low-temperature service, our cryogenic ball valves are built to maintain seal integrity down to -150°C, suitable for liquefied gas, LNG, and other cryogenic transfer lines. We manufacture valve bodies in both forged and cast steel, depending on the pressure class and application, and our trunnion-mounted line is available in API 6D-certified configurations for buyers who need documented compliance for oil and gas projects.

Quick Shut-Off and High-Sealing Performance

Our ball valves use a quarter-turn design so that operators can move from fully open to fully closed with a 90-degree turn, faster and with less wear than multi-turn valves like gate valves. Seats are available in PTFE, RPTFE, and metal-seated options depending on temperature and pressure requirements, giving a tight shutoff that limits leakage past the seal. Because the seats carry the sealing load rather than the body, replacement is a simpler maintenance task when it's eventually needed.

Low Pressure Drop for Consistent Flow

Full-bore ball valves open to the same internal diameter as the connecting pipe, so fluid passes through without the flow restriction that reducing-bore designs create. That translates to less turbulence, lower energy loss across the line, and steadier flow rates in continuous-duty applications. For buyers running long pipeline segments, that difference compounds over distance in a way a partial-bore valve can't match.
