Three-piece Ball Valve

Dafugui's three-piece ball valves are manufactured using precision CNC machining and automated assembly technology, ensuring that each valve maintains stable performance under harsh conditions such as high pressure and high temperature.

The connecting sections at both ends and the middle valve body of the three-piece ball valve can be flexibly disassembled and assembled. Compared with traditional one-piece or two-piece ball valves, it has advantages in sealing performance and service life. It can not only quickly and completely shut off the medium flow, but also allow you to control the flow rate very precisely. If your working environment requires frequent switching operations or has particularly high sealing requirements, it can absolutely perform perfectly and is very reliable.

Core Parameters

Advantages

1. Versatile Functionality, Wide Range of Applications

This three-piece ball valve can reliably and completely cut off the medium in the pipeline when used as an on/off valve. It can also flexibly handle situations requiring flow control.

It can also flexibly handle situations where traffic volume needs to be controlled. Its valve seat opening size changes synchronously with the valve disc movement distance, resulting in exceptionally precise flow regulation. Whether you want to increase or decrease the flow, it's easily controllable, making it ideal for both raw material transportation in the chemical industry and medium flow rate control in the petroleum industry.

2. Easy Operation, Reliable Sealing

The valve stem's opening and closing strokes are relatively short, requiring minimal effort to operate. Even with frequent switching, it's effortless for operators. Furthermore, this three-piece ball valve boasts exceptionally reliable shut-off function, excellent sealing performance, and a low media leakage rate.

Multiple material options are available, including carbon steel, heat-resistant steel, stainless steel, and duplex steel. 3. Reasonable structure and convenient maintenance: The three-section structural design is particularly reasonable, facilitating both installation and disassembly. Subsequent maintenance does not require removing the entire valve from the pipeline; simply disassembling the three sections allows for easy inspection of internal parts, saving both time and manpower. It complies with authoritative standards such as API 6D and GB/T12237, meeting the requirements of both domestic and export projects.
