Does the actuator on the oxygen valve need to be anti-static and explosion-proof?
Thread Content
As the title suggests, I would like to ask the experts here: do the actuators of oxygen valves used in coal chemical industry oxygen pipelines need to be anti-static and explosion-proof?
GB 50030-2013 Code for Design of Oxygen Stations, Article 8.0.8: All types of equipment for storing liquid oxygen and liquid air, oxygen compressors, oxygen filling stations, and oxygen pipelines shall be equipped with anti-static grounding devices, and the grounding resistance shall not exceed 10Ω.
Antistatic properties are necessary. Explosion protection is relevant to electrical accessories; there is no such concept as explosion protection for valves themselves. . . .
Pneumatic versions are not explosion-proof; electric versions must be explosion-proof
Anti-static protection is definitely necessary, while for explosion prevention it depends on the type of valve being used; different approaches are required in each case.
