H21X high pressure gas check valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and H21X different effect of high pressure gas check valve, from ball Industrial Valves and H21X distinguish between high pressure gas check valve structure. 【 Functional difference between 】 H21X high-pressure gas check valve is mainly used for gas pipeline, main effect is to prevent the reverse flow of gas, is suitable for air, CNG gas pipeline, such as natural gas, hydrogen attention when installation should pay special attention to flow direction of medium, should make medium and normal flow direction of arrow on valve body direction is consistent, otherwise it will be truncated normal flow of the medium. Ball Industrial Valves and high pressure gas H21X check difference is bigger, ball valve, 球阀) Opening and closing is a sphere, driven by the valve 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 】 H21X high pressure gas check Industrial Valves ball valve' Summary 】 H21X high pressure gas check valve and ball valve and using 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, whether at design time, or in the purchase, must be in strict accordance with the relevant technical requirements.
