Applications for globe valves: Part 4

7. Globe valve for oxygen pipeline: The valve is designed in strict accordance with the requirements of oxygen pipeline. The stuffing box part is strictly sealed, and external dirt must not enter the stuffing box. There are grounding devices at the flanges at both ends of the valve body, and after the installation on the pipeline, it should be grounded to prevent static fire. The housing material of the valve is austenitic stainless steel or copper, which conducts electricity well and is not prone to electrostatic fire. The sealing material is PTFE to the valve body material, which is a soft seal, good sealing performance, and zero gas test leakage. The valve is strictly degreased by carbon tetrachloride before assembly, and there is absolutely no grease and dirt, which will not cause static ignition. The valve is suitable for oxygen lines in metallurgical systems and also for oxygen lines in other industries.

8. Petroleum liquefied gas globe valve: This valve is specially designed for the pipeline and device of petroleum liquefied gas. Attention is paid to fire protection requirements in the structure. The filler is made of polytetrafluoroethylene, which is reliably sealed and absolutely free of leakage. The sealing sub-material adopts polytetrafluoroethylene or nylon to the valve body material, which is a soft seal and reliable sealing. The valve is suitable for LPG piping systems, as an opening and closing device, and is also suitable for other pipelines with a temperature of 《80^oC.
