關于蝶閥電動執行器的主要特點
About the butterfly valve electric actuator

隨著閥門電動執行器的發展，目前國內外有很多企業，現在蝶閥電動執行器在實際應用中越來越廣泛在技術，產品以的品質和完善的售后服務贏得廣大客戶青睞。電動蝶閥連接方式主要有：法蘭式和對夾式。電動蝶閥屬于電動閥門和電動調節閥中的一個品種。電動蝶閥密封形式主要有：橡膠密封和金屬密封。電動蝶閥通過電源信號來控制蝶閥的開關。該產品可用做管道系統的切斷閥，控制閥和止回閥。附帶手動控制裝置，一旦出現電源故障，可以臨時用手動操作，不至于影響使用。電動蝶閥是以電動執行器與蝶閥的的結合而稱謂，相同需要的扭力配置以符合通用的SIO5211連接標準平臺以及互為的±5°微調，而達到精密協和。
With the development of electric valves, there are many well-known companies at home and abroad. Nowadays, electric butterfly valves are more and more widely used in practical applications. The products are favored by customers with excellent quality and perfect after-sales service. The connection methods mainly include: flange type and clamp type. Electric butterfly valve is a kind of electric valve and electric regulating valve. Electric butterfly valve sealing form mainly include: rubber seal and metal seal. The electric butterfly valve controls the switching of the butterfly valve through the power signal. This product can be used as shut-off valves, control valves and check valves of piping systems. With manual control device, once a power failure occurs, manual operation can be performed temporarily without affecting the use. Electric butterfly valve is the perfect combination of electric actuator and butterfly valve. The same required torque configuration complies with the internationally accepted SIO5211 connection standard platform and mutual fine adjustment of ±5° to achieve precise convergence.
