H44H, H44W cast steel flange check valves and ball valves difference is large, we can distinguish from the function to go up and ball valve and H44H, H44W cast steel flange check valves of different effects, from ball valve and H44H, H44W cast steel flange check valves structures. 【 Functional difference between 】 H44H, H44W cast steel flange check valves for pressure 1. 6 ~ 25 mpa - operating temperature 29 ~ + 550 ℃ in the petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, such as the pipeline under various working conditions, its main role is to prevent the backflow medium, to prevent the pump and its pattern in reverse driving voltage, and the discharge of the containers within the medium, suitable medium such as water, oil, steam, acid medium. Widely used in petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, low temperature under various working conditions such as the pipeline. Ball valve and H44H, H44W cast steel flange check valves difference is bigger, ball Industrial Valves, 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 】 H44H, H44W cast steel flange check valves ball valve Summary 】 H44H, H44W cast steel flange check Industrial Valves 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.
