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.

Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.
