关于蝶阀电动执行器的主要特点
About the butterfly valve electric actuator
随着阀门电动执行器的发展，目前国内外有很多企业，现在蝶阀电动执行器在实际应用中越来越广泛在技术，产品以的品质和*的售后服务赢得广大客户青睐。电动蝶阀连接方式主要有：法兰式和对夹式。电动蝶阀属于电动阀门和电动调节阀中的一个品种。电动蝶阀密封形式主要有：橡胶密封和金属密封。电动蝶阀通过电源信号来控制蝶阀的开关。该产品可用做管道系统的切断阀，控制阀和止回阀。附带手动控制装置，一旦出现电源故障，可以临时用手动操作，不至于影响使用。电动蝶阀是以电动执行器与蝶阀的的结合而称谓，相同需要的扭力配置以符合通用的SIO5211连接标准平台以及互为的±5°微调，而达到精密协和。
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.
