TFA72W vacuum negative pressure relief valve and ball valve difference is bigger, we can distinguish from the function to go up and the different function of ball Industrial Valves and TFA72W vacuum negative pressure relief valve, can also went up from ball valve and TFA72W vacuum negative pressure relief valve structure. 【 Functional difference between 】 TFA72W vacuum negative pressure relief valve is suitable for the temperature of 200 ℃ or less negative pressure system, when the container pressure exceeds allowable values, vacuum negative pressure relief valve automatically opens, inhaled air; When the container pressure to allowable values, TFA72W - 10 p/R vacuum negative pressure relief valve shut down automatically, thus protecting equipment and systems. Ball valve and TFA72W vacuum negative pressure difference is bigger, relief valve 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 】 【 TFA72W vacuum negative pressure relief Industrial Valves ball valve Summary 】 TFA72W vacuum negative pressure relief valve and ball Industrial Valves 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.
