Pneumatic two-way threaded ball valve, pneumatic ball valve

The pneumatic two-way threaded ball valve is composed of a piston-type pneumatic actuator and an internal-threaded three-piece ball valve. The three-piece ball valve consists of a main valve body and two auxiliary valve bodies, and the auxiliary valve bodies are machined with internal threads. Four bolts are used to connect the main and auxiliary valve bodies together. Its advantage is that when repairing and disassembling, there is no need to remove the pipe thread, but only the four bolts can be removed directly. The middle part of the valve body can be taken out, which is convenient for replacing the valve seat sealing ring. Pneumatic three-piece hard-sealed ball valve body is installed without a bracket with the pneumatic actuator, which is convenient and reliable.

Pneumatic two-way threaded ball valve can be installed with various accessories, facilitating remote automatic control. Pneumatic threaded three-piece ball valve adopts intelligent control and positioning, and is matched with an electrical valve positioner. By inputting a 4-20 mADC signal and 0.4-0.7 MPa air source, it can control the operation and realize the regulation of parameters such as pressure, flow, temperature, and liquid level.

It is driven by compressed air, and the valve stem drives the valve core to rotate 90 degrees to achieve the action of opening and closing.

The product features of pneumatic threaded ball valve:

At present, this valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and research equipment, power, etc.

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe section.

2. The structure is simple, the volume is small, and the weight is light.

3. It is tight and reliable. The sealing surface material of the ball valve is widely used in plastics at present, and the sealing performance is good. It has also been widely used in vacuum systems.

4. The operation is convenient, the opening and closing are rapid, and only 90 degrees rotation is required from full open to full close, which is convenient for remote control.

5. Maintenance is convenient. The valve body structure is simple, and the sealing ring is usually movable. The disassembly and replacement are relatively convenient.

6. When fully open or fully closed, the sealing surface of the ball and the valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.

7. The application range is wide. The diameter can be from a few millimeters to several meters, from high vacuum to high pressure, and can be applied.

The application fields of pneumatic two-way threaded ball valves include:

Food industry: Suitable for fluid control systems in food processing and handling processes.

Environmental protection industry: Can be used in fluid control systems of environmental protection equipment.

Light industry: Used in various medium control in light industry production.

Petroleum industry: Suitable for fluid control in petroleum extraction, refining and transportation processes.

Paper industry: Used in fluid control systems in paper production processes.

Chemical industry: Suitable for fluid control in chemical production, including the treatment of corrosive media.

Teaching and research equipment: Used for fluid control in teaching and research equipment.

Electric power industry: Used for fluid control systems in power production.
