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.

CW700 Series Bellows Seal Control Valves are divided into three major series: CSW701/CW701/CW702/CLW702 type bellows-sealed single-seat regulating valves and bellows-sealed cage-type regulating valves, as well as low-leakage bellows-sealed cage-type regulating valves. The bellows-sealed single-seat regulating valve is a regulating valve with top guide structure. The bellows-sealed cage-type regulating valve is a regulating valve with pressure balance. The valve body has an S-flow channel type passage, with small pressure drop loss, large flow rate, wide adjustable range and high flow characteristic accuracy. The low-leakage bellows-sealed cage-type regulating valve not only has the advantages of cage-type regulating valves, but also has a sealing ring between the valve core and the valve cage, reducing the leakage. The full series of upper valve covers adopt bellows-sealed structure, which can completely eliminate the possibility of medium leakage from the valve stem movement gap to the outside. When equipped with the RSMF series actuators, it has a compact structure, large output force and long service life. Therefore, it is widely used in automatic control systems of highly toxic, strongly corrosive, radioactive and rare and precious media. *CSW701Bellows Seal small-Port single-seat control valve *CW701 Bellows Seal single-seat control valve *CW702 Bellows Seal caged globe control valve *CLW702 Bellows Seal Low-leakage bellows caged globe control valve
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
The Rotary Ball Valve adopts advanced ball rotation sealing technology and is specially designed for harsh working conditions. It is suitable for the control of high-pressure, high-temperature and corrosive media in industries such as petroleum, chemical engineering, natural gas, and power. Its unique rotating valve seat structure effectively reduces friction and wear, ensuring more durable sealing performance and easier operation. The valve body is made of high-quality stainless steel, carbon steel or special alloy materials, and is precisely processed and hardened to ensure long-term stable operation. It supports various driving methods such as manual, pneumatic, and electric, meeting different automation requirements and is an ideal choice for industrial pipeline fluid control.
