WJ61H butt welding bellows globe valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and WJ61H butt welding different role of corrugated pipe cut-off valve, from ball valve and distinguish WJ61H welded bellows globe Industrial Valves structure. 【 Functional difference between 】 WJ61H butt welding bellows globe Industrial Valves adopts double durable bellows seal design ( Bellows + packing) To ensure the zero leakage of the stem. No fluid loss, improve plant safety equipment, and in accordance with international standard seal. Butt welding bellows globe valve sealing surface surfacing welding Co in cemented carbide, wear-resisting, corrosion resistance, resistance to friction performance is good, long service life. Stem conditioning and surface nitriding treatment, good corrosion resistance and friction resistance; Stem lifting position indicator, more intuitive. Ball valve and WJ61H welded bellows globe valve 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 】 WJ61H butt welding bellows globe valve ball valve' Summary 】 WJ61H butt welding bellows globe 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, no matter when the design, or in the purchase, must be in strict accordance with the relevant technical requirements.
