JOUCOMATIC电磁阀ZBF24Q-10型自保持球阀主要是由阀体和驱动机构组成，是一种自保持阀门。在接到开（关）阀信号后，驱动机构得电带动球阀阀芯转动，阀芯转到位后电动执行机构内部自断电，阀位机械指示指向相应的阀位，阀位开关输出无源阀位信号。阀芯每转90°，阀功能切换一次。ZBF24Q-10型自保持球阀采用球面密封结构，无内漏，比传统滑阀结构电磁换向阀密封更好。 　　
不存在滑阀无法克服的液压卡紧力，因而对于长时间不操作的油缸无需为防止液压卡紧力而定时切换。 　　
驱动机构采用全套进口产品，防护等为IP65,阀体所有零件均采用不锈材料制造，适于在潮湿的环境下工作。对介质清洁度不作严格要求。
阀位置有现场机械显示和开关接点输出。 　　
The monostable spool valves, series 551, have TÜV certifi ed IEC 61508 Functional
Safety data and can be used up to SIL 4/AK 7
The spool valves 3/2 NC have threaded port connections
All the exhaust ports of this spool valve are connectable, providing better environmental
protection, particularly recommended for sensitive areas such as clean
rooms, and applications in the pharmaceutical and food processing sectors
The valve offers environmental protection against the ingress of liquids, dusts or
any other foreign matter （environmentally-protected construction）
Can be externally piloted （external air pilot supply） to convert valve to zero minimum
operation by fl ipping a gasket
The solenoid valves satisfy all relevant EC Directives
