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.

Scope of Application: Single-drive double ball valve is widely used in situations where two fluid channels need to be controlled simultaneously, such as fluid control systems in chemical, petroleum, natural gas, metallurgy and other industries. Single-drive double ball valve can play an important role in situations where precise control of fluid flow, pressure and direction is required.
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.
The Forged Steel Compact Globe Valve is a high-performance fluid control device, precision-engineered from premium forged steel material. It combines throttling and shut-off functions in one unit. Designed specifically for high-pressure and high-temperature applications, it features compact construction, reliable sealing, and extended service life, making it ideal for demanding conditions in petroleum, chemical, power, and other industries.
Stop Check Valve, A multi-purpose valve that functions as both a stop valve and a check valve. Its structure is similar to that of a globe valve, but the stem and disc are not fixed. When the stem is lowered and the disc is pressed tightly on the seat, it acts as a stop valve; After the stem rises, the check valve acts. On lines that require both a stop valve (or gate valve) and a check valve (such as the outlet of a water pump), using a stop check valve can save installation costs and space. In the opening and closing process, because the friction between the valve disc and the sealing surface of the valve body is smaller than that of the gate valve, it is more wear-resistant.
