A42H oxygen, A42Y stainless steel relief valve and ball valve difference is large, we can distinguish from the function to go up and ball valve and the different function of oxygen A42H, A42Y stainless steel relief valve, from ball valve and distinguish A42H, oxygen A42Y stainless steel relief valve structure. 【 Functional difference between 】 A42H oxygen, A42Y stainless steel relief valve is suitable for the working temperature of 300 ℃ or less medium such as air, oxygen, liquefied petroleum gas (LPG) of equipment and piping. A42Y - P type and A42Y - R type is suitable for the working temperature of 200 ℃ or less corrosive medium of equipment and piping, as the overpressure protection device. - The 94 series. ≥6. - The 94 series. Ball valve and A42H, oxygen A42Y stainless steel relief valve, the difference is larger, ball valve, 球阀) Opening and closing is a sphere, driven by the Industrial Valves stem, and for ball valve axis rotate 90 & deg; Open or closed. Can also be used on regulation and control of fluid, mainly used for cutting in line, distribution, and change the flow direction of medium, good sealing, convenient operation, opening and closing fast, simple structure, small volume, small resistance, light weight, etc. 【 Physical difference between 】 A42H, oxygen A42Y stainless steel relief valve, ball valve' Summary 】 A42H oxygen, A42Y stainless steel relief valve and ball valve and the difference function, are quite different in application, in the selection of a certain need to pay special attention to diameter, pressure, material and use of media, no matter when the design, or in the purchase, must be in strict accordance with the relevant technical requirements.
