Frequently Asked Questions
1. What Is the Difference Between an Oxygen Valve and a Standard Globe Valve?
Valves designed specifically for oxygen must take into account the characteristics of oxygen as a medium, with particular emphasis on material compatibility, internal cleanliness, and installation and usage requirements.
Even if they have the same pipe diameter and pressure rating, standard globe valves cannot be used directly in oxygen piping without undergoing an oxygen suitability assessment.
For oxygen applications, degreasing, cleaning, inspection, and acceptance requirements must also be confirmed in accordance with project specifications.
2. What Materials Are Available for Oxygen Globe Valves?
The JY41W series includes valve body configurations made of both stainless steel and copper alloys.
The choice of material should be based on the pressure, temperature, and material compatibility of the oxygen system, as well as the project’s technical specifications, rather than solely on price.
If your project specifies a particular material grade, please provide the technical requirements when requesting a quote so we can verify them further.
3. Can Oxygen Valves Be Used for High-Pressure or Cryogenic Oxygen Service?
If your application involves higher pressures, liquid oxygen, or cryogenic temperatures, you must independently verify the appropriate materials, design, and applicable standards; standard room-temperature oxygen valves cannot be used as direct substitutes.
4. How Do I Select the Right Oxygen Valve Size?
When selecting an oxygen valve, you need to comprehensively consider the pipe size, medium flow rate, operating pressure, and connection requirements.
If you have already determined the pipe DN, you can further match the valve by referring to the size chart for the corresponding JY41W model.
If the specifications have not yet been determined, we recommend providing the actual operating conditions and pipe design parameters to facilitate model selection and verification.
5. Do Oxygen Valves Require Special Cleaning Before Installation?
Oxygen systems have strict requirements regarding grease, particulates, and other contaminants inside valves.
Therefore, when purchasing valves specifically designed for oxygen systems, it is important to clearly define the degreasing and cleaning standards, cleaning validation, packaging, and on-site installation requirements applicable to the project.
If you require relevant cleaning or testing documentation, it is recommended that you request it during the request-for-quote stage to confirm the technical delivery conditions for the specific order.
