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.
◎ Design Standard: API 6D,API 608,GB/T12237

◎ Application scenarios: Widely used in situations where two pipelines need to be controlled simultaneously, such as liquid pipelines in refrigeration and air conditioning systems. Due to its simple operation, precise flow control, and good corrosion resistance, it is suitable for various fluid media, including gases, liquids, and vapors
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
RAYS Side Entry Floating Ball Valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS 5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims.
RAYS Blind Valve features an advanced design for quick and safe flow isolation or fluid control within pipelines. At the heart of the valve is a blind plate that can be swiftly moved in and out by turning a handwheel. To isolate the flow, simply turn the handwheel and the blind plate will slide along a track to the center of the pipe, creating a seal that blocks fluid flow. This operation does not require any special tools, nor does it involve dismantling heavy machinery or dealing with complicated bolts and nuts. The design of the blind plate ensures a stable and reliable sealing performance in any working condition, greatly simplifying the operation and reducing operational risks. The simplicity and durability of the structure also make maintenance straightforward, reducing both maintenance costs and downtime.
