Product Details


Stainless Steel Oxygen Special Ball Valve Product Introduction

Stainless steel oxygen specific ball valveYQ347F, YQ347PPL, YQ347Y oxygen ball valve, oxygen flange ball valve, stainless steel oxygen ball valve, as opening and closing devices on oxygen pipelines in the metallurgical industry, have many particularly strict requirements compared to other general-purpose valves. Because oxygen is a flammable and explosive hazardous material, it is necessary to prevent leakage, static electricity, and fire flowers to avoid accidents. Structurally, it is designed such that when the valve disc opens and closes, the valve stem only rises and falls without rotating, effectively reducing the wear of the sealing pair, packing, and upper seal; The side flange is equipped with grounding screws to prevent the generation of static sparks; The exposed part of the valve stem is sealed with organic glass to prevent dust and oil. The valve body material 1Cr18Ni9Ti has the advantages of good sealing performance, easy and flexible operation, safety and reliability, and long service life.
