The globe valve used for oxygen(O₂) medium pipeline is designed and manufactured according to the operating characteristics of oxygen pipeline network and considering the flammable and explosive characteristics of oxygen medium, with safety, reliability and superior performance as design principles, and with reference to relevant regulations. Special valve for safe operation of pipeline network. The main material is made of stainless steel or copper alloy with excellent flame retardancy, the sealing surface is made of body or surfacing D802, and the rest of the internal parts are made of stainless steel or copper alloy; the transmission parts are lubricated with non-flammable grease, and marked with obvious oil prohibition. Structurally, the bracket is fully enclosed, and is designed with a static elimination device, and the valve stem is equipped with a dust cap.

The main features of Globe Valve for oxygen(O₂) media are as below:

1. Flame retardant and flame retardant: The material of the main components is copper alloy, which is a non-flammable material. Even if it collides with solid particles in a high-speed airflow, it will not produce sparks. Therefore, the valve has the best flame retardant properties.

2. Safe and reliable: The valve is equipped with dust-proof, waterproof and oil-proof devices. All valve parts in contact with oxygen are strictly degreased and oil-free before assembly. The packing material is polytetrafluoroethylene, which can ensure the safety of use. reliable

The following matters need to be paid attention to during installation, use and maintenance:

1. During the transportation and storage of the oxygen(O₂) globe valve, attention should be paid to preventing rain, moisture and oil.

2. The pipeline or accessory flange gasket connected to the globe valve should be annealed and softened aluminum sheet, copper sheet or copper wire.

3. In order to prevent fire, a copper-based alloy (or stainless steel) pipe should be connected before and after the stop valve with a working pressure greater than 0.6MPa, the length should not be less than 5 times the pipe diameter, and not less than 1.5m, and no pipe fittings should be installed.

4. After the stop valve is installed on the pipeline, the system strength tightness and leakage test should be carried out according to the system design regulations, and special cleaning treatment should be carried out.

5. A fixed platform should be set next to the manual valve for easy operation and maintenance. Manual ball valves with a diameter larger than 70mm are only allowed to operate when the pressure difference between the front and rear of the valve is within 0.3MPa. When operating, stand on the side of the valve and operate slowly. Cannot be used for adjustment.

6. After the stop valve is out of use for a long time, it should be thoroughly cleaned with special cleaning treatment when it is used again.

7. For valves that are frequently operated, try to use pneumatic control valves.
