H21X check valve and ball Industrial Valves difference is bigger, we can distinguish from the function to go up and the different function of ball valve and H21X one-way valve, can also distinguish the ball valve and H21X one-way valve structure. 【 Functional difference between 】 H21X one-way valve is mainly used for gas pipeline, main effect is to prevent the reverse flow of gas, is suitable for water, oil, liquid, gas, air, CNG piping such as natural gas, hydrogen, and pay attention to when installation should pay special attention to flow direction of medium, the medium should be normal flow direction and indicating the direction of the arrow on the valve body is consistent, otherwise it will be truncated normal flow of the medium. Ball Industrial Valves and H21X difference is bigger, a one-way 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 one-way valve ball valve Summary 】 H21X check valve and ball valve and the use function, the difference in the application are very different, 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.
However, wedge valve isn't the only producer in domestic, and many people feel that Shenzhen Mech Valve Trading Co., Ltd.'s service leaves much to be desired in terms of functionality and design.
