德国top托普电动球阀概述： 电动球阀结构简单、由几个零件组成、资源用料省、体积小、重量轻、操作简便，只需旋转90°即可快速启闭。采用一体化结构，以单相电源ac220v和直流电源24vdc即可控制运转；体积小、轻便、性能可靠、配套简单、流通能力大等优点。 电动球阀具有如下的一些优点： 流体阻力小，球阀是所有阀类中流体阻力小的一种，即使是缩径球阀，其流体阻力也相当小。 开关迅速、方便，只要阀杆转动90°，球阀就完成了全开或全关动作，很容易实现快速启闭。 密封性能好。球阀阀座密封圈一般采用聚四等弹性材料制造，易于保证密封，而且球阀的密封力随着介质压力的增加而增大。 阀杆密封可靠。球阀启闭时阀杆只作旋转运动，因此阀杆的填料密封不易被破坏，而且阀杆倒密封的密封力随着介质压力的增加而增大。 球阀的启闭只做90°转动，故容易实现自动化控制和远距离控制，球阀可配置气动装置、电动装置、液动装置、气液联动装置或电液联动装置。 德国top托普电动球阀技术参数： 阀体材料：wcb、304、316 阀门口径：dn15-600 阀门压力：pn16-pn64 连接标准：asme b16.10、din2501 控制方式：手动、气动、电动 密封材料：ptfe、304 工作温度：-20℃至+150℃（可以定制350℃） 德国top托普电动球阀应用领域： 水、蒸汽、油品、天然气等流体 the german top top electric ball valve: electric ball valve structure is simple, composed of several parts, resources, material saving, small size, light weight, easy to operate, simply rotating 90 degrees, you can quickly open and close. with the integrated structure, the single-phase power supply ac220v and the dc power supply 24vdc can control the operation. the utility model has the advantages of small size, portability, reliable performance, simple matching, large circulation capacity, etc.. electric ball valves have some of the following advantages: fluid resistance is small, the ball valve is the smallest of all types of fluid resistance, even if the diameter of the ball valve, its fluid resistance is quite small. switch quickly and easily, as long as the valve rod to rotate 90 degrees, the ball valve is completed fully open or fully closed action, it is easy to achieve rapid opening and closing. good sealing performance. ball valve seat ring is generally made of ptfe and other elastic materials, easy to ensure sealing, and the sealing force of the ball valve as the pressure increases with the increase. reliable stem seal. when the ball valve opens and closes, the valve stem is only rotated, so the packing seal of the valve stem is not easy to be damaged, and the sealing force of the valve stem sealing is increased with the increase of the medium pressure. valve opening and closing only 90 degrees rotation, it is easy to achieve automatic control and remote control, the ball valve can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage or electro-hydraulic linkage device. germany top top electric valve technical parameters: body material: wcb, 304, 316 valve bore: dn15-600 valve pressure: pn16-pn64 connection standards: asme, b16.10, din2501 control mode: manual, pneumatic, electric sealing materials: ptfe, 304 operating temperature: -20 deg c to +150 c (350 deg c can be customized) germany top top electric valve applications: water, steam, oil, natural gas and other fluids su wen bin (苏文宾） please do not hesitate to contact me if you need any further clarifications ; 3202186864 mobile phone : (同号） company phone :021-64387268 add : 上海徐汇区龙漕路51弄
