To maintain the integrity of the process logic , manual air supply overrides for control and automated valve actuator solenoids are not permitted 为保持工艺控制的完整性，控制器与自动阀门执行机构的电磁阀不许手动供气取代自动控制。
The port labeled as boost port 2 is also a port that will provide access to boost pressure , but it is normally connected to the bypass valve actuator and should be left alone 港口被给贴标签帮助港口2也是将提供进入的途径的一港口推进当时压力，但是它通常连接支路阀门作动器并且应该被单独留下。
The electric valve actuating controller is a main section of the electric valve actuator . the author in this master paper analyzes in detail and deeply the electric valve actuators and their controllers at home and abroad , and adopts to some experience successfully 阀门电动装置控制器是阀门电动装置的核心部件。本文对现有的国内外阀门电动装置及其控制器进行了深入和详尽的对比和分析，借鉴和传承了它们的有效的成功经验。
Particularly in cases where valve actuators are activated at irregular intervals or not at all over an extended period of time , the advantages of the overload resistance of pneumatic drives become apparent , since deposits or caking can lead to considerably increased breakaway torques 此气动驱动装置尤其在不定期开启或长时间关闭阀门制动器的情况下才能明显体现其优势，因为（内燃机里的）沉积或烧结物会引起起步转矩逐渐增加。
The hydraulically actuating , electronically controlled variable valve actuator , the common rail hydraulical source and the electronic control unit have been designed and developed . the primary control strategies of the valve timing in different conditions have been discussed . the performance of the system has been researched deeply by experiments , from which , plenty of rules have been obtained , and the way to adjust valve timing , lift and duration has been put forward 研制了电控可变气门系统的执行器? ?电控可变气门驱动机构，设计了电控可变气门系统的液压驱动源? ?中压共轨液压源，开发了电控可变气门系统的电子控制单元，实现了在不同工况下，气门正时、气门开启持续期、气门升程柔性的电子控制，并对不同工况下配气正时的控制策略进行了初步探讨。
