H44H, H44W day standard swing check valve and ball valve difference is bigger, we can distinguish from the function to go up and ball Industrial Valves and H44H, H44W day mark the different function of swing check valves, from ball valve and H44H, H44W Japanese standard to distinguish swing check valve structure. 【 Functional difference between 】 H44H, H44W day standard swing check valves are widely applied in 10 k - nominal pressure 20 k, 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 Industrial Valves and H44H, H44W day standard difference is bigger, swing check valve 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 】 H44H, H44W day standard swing check valve ball Industrial Valves' Summary 】 H44H, H44W day standard swing 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.
