safety instructions for American go pressure reducing valve:

1. Check the pressure regulating valve before each use

2. Before installing the pressure regulating valve, it is necessary to clarify the flow direction of gas. The user is responsible for installing the equipment in the correct direction

3. It is forbidden to connect the pressure regulating valve to the pressure source whose pressure is higher than the ZD rated pressure of the pressure regulating valve

4. In the pressure bearing system, it is not allowed to fasten the pipe fittings, pressure gauges or missing parts

5. If the regulating valve leaks or fails to work, it must be replaced immediately

6. Pressurize the system step by step to avoid sudden gas or pressure impact on the system equipment

7. The pressure regulating valve is not a stop device. A pressure relief device shall be installed downstream of the pressure regulating valve to protect the equipment from the increase of working pressure. When the pressure regulating valve is not used, turn off the transmission

Inlet pressure

8. In order to ensure continuous and safe work, the equipment needs to be inspected and maintained regularly

9. The frequency of maintenance depends on the user's use

10. Carefully read and observe the precautions on the label of the compression cylinder

11. The use of oxygen requires expertise and knowledge in system design and material compatibility to ZD minimize the possibility of death, serious injury and / or property damage

Sex

12. Pressure regulating valve or accessory materials that do not match the gas used shall not be used

13. The user must test according to the normal working conditions and determine the suitability of the material for this purpose

14. The pressure regulating valve using flammable gas shall not be close to the open fire or any ignition source

15. Some gases do not have a visible flame when burning. Special care should be taken when inspecting and / or maintaining systems using flammable gases to prevent death or serious injury

The accident happened. Use a device to warn employees of such hazards

16. Do not use grease on such pressure regulating valves. Grease is flammable and reacts violently with some gases under high pressure

17. If toxic or flammable gases are used in such areas, emergency equipment shall be equipped

18. Do not loosen the pipe fittings to discharge the gas in the system

19. Remove the excess water in the gas to prevent the equipment from freezing

20. It is recommended to use filters upstream of all gases
