H41H, H41W din flange check valves and ball valves difference is large, we can distinguish from the function to go up and ball valve and H41H, H41W din flange check valves of different effects, from ball valve and H41H, H41W din flange check valves structures. 【 Functional difference between 】 H41H, H41W din PN16 flange check valves are widely applied in the nominal pressure - PN40, working temperature - 29 ~ 550 ℃ in the petroleum, chemical, thermal power plant under various working conditions such as piping, applicable medium: water, oil, steam, etc. 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. Ball valve and H41H, H41W din 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 Industrial Valves 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 】 H41H, H41W din flange check valves ball valve 【 Summary 】 H41H, H41W din flange 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.
