H64Y, H44Y forged steel swing check valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and H64Y H44Y forged steel swing check valve of different roles, from ball valve and H64Y H44Y forged steel swing check valve structures. 【 Functional difference between 】 H64Y, H44Y forged steel swing 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 valve and H64Y H44Y forged steel swing check valves 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 】 H64Y, H44Y forged steel swing check Industrial Valves ball valve' Summary 】 H64Y, H44Y forged steel swing 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.
