H41Y, H41H forged steel flange end check valve and ball valve difference is large, we can distinguish from the function to go up and ball valve and H41Y H41H forged steel flange end check different effects, can also from the ball valve and H41Y, H41H forged steel flange end up check valve structure. 【 Functional difference between 】 H41Y, H41H forged steel flange end check valve sealing surface with iron base alloy or state department ( Stellite） Cobalt-based hard alloy welding surface into wear-resisting, high temperature resistance, good corrosion resistance, abrasion resistance, long service life, etc. Stainless steel pin is used to connect with the disc - built in structure High performance - Seal is more reliable. Products are widely used in petroleum, chemical, pharmaceutical, electric power industries under different conditions, such as the pipeline medium backflow prevention role. Applicable medium for water, oil, steam, gas and some corrosive liquid medium, etc. Ball Industrial Valves and H41Y H41H forged steel flange end 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 】 H41Y, H41H check valve ball valve forged steel flange end 【 Summary 】 H41Y, H41H forged steel flange end check valve and ball valve and 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, no matter when the design, or in the purchase, must be in strict accordance with the relevant technical requirements.
