1. Structure: The single-drive double ball valve consists of two ball valves sharing a valve body and a drive device (such as a handle, gear, electric or pneumatic actuator). The balls and valve seats of the two ball valves are usually independent, but they are connected by a common drive shaft.
2. Synchronous Operation: Since the two ball valves share a drive device, they can be opened or closed at the same time, ensuring that the fluid flow or isolation operation in the two pipelines is carried out synchronously.
3. Save Space: Compared with installing two independent ball valves, the single-drive double ball valve can save space and reduce the complexity of pipeline connection.
4. Reduce Driving Devices: Only one drive device is needed to control two ball valves, which can reduce costs and maintenance workload.
5. Application Flexibility: Double ball valves can be designed into different sizes and pressure levels as needed to suit different applications.

Forged steel globe valve is a high-performance fluid control equipment, manufactured with high-quality forged steel materials and precision, integrating throttling and shut-off functions. Specially designed for high-pressure and high-temperature working conditions, it has the characteristics of compact structure, reliable sealing, and long service life, and is widely used in harsh working conditions in industries such as petroleum, chemical, and power.
The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
The Side Entry Trunnion mounted ball valves are quarter-turn valves used to stop the flow of medium in pipelines. RAYS is the real API 6D valve manufacturer for the Trunnion mounted ball valve. These valves feature a round or spherical disk in the center that rotates to start or stop the flow. This disk is called a ball and it features a hollow center. Ball valves are extremely versatile and are commonly used in industrial applications where tight shut-off is required.
