H61Y, H64Y forged steel since the check valve and ball Industrial Valves sealing difference is large, we can distinguish from the function to go up and ball valve and H61Y H64Y forged steel since the seal check different effects, from ball valve and H61Y H64Y forged steel up to distinguish from a seal check valve structure. 【 Functional difference between 】 H61Y, H64Y forged steel since the seal check valve is pressure self-tightening type bonnet, according to the form design of the valve, the valve body and bonnet with threaded connections, internal pressure since the ring seal. The higher the cavity pressure in the sealing performance, the better. Disc and seat sealing surface using hard alloy surfacing and become, has a high temperature resistant scour, the characteristics of wear resistance, is used in high temperature and high pressure steam, oil and other medium ideal valve. Ball valve and H61Y H64Y forged steel since the seal 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 】 H61Y, H64Y forged steel since the seal check valve ball valve' Summary 】 H61Y, H64Y forged steel since the check valve and ball valve sealing difference on and use 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.
