JOUCOMATIC電磁閥ZBF24Q-10型自保持球閥主要是由閥體和驅動機構組成，是一種自保持閥門。在接到開（關）閥信號后，驅動機構得電帶動球閥閥芯轉動，閥芯轉到位后電動執(zhí)行機構內部自斷電，閥位機械指示指向相應的閥位，閥位開關輸出無源閥位信號。閥芯每轉90°，閥功能切換一次。ZBF24Q-10型自保持球閥采用球面密封結構，無內漏，比傳統滑閥結構電磁換向閥密封更好。 　　
不存在滑閥無法克服的液壓卡緊力，因而對于長時間不操作的油缸無需為防止液壓卡緊力而定時切換。 　　
驅動機構采用全套進口產品，防護等為IP65,閥體所有零件均采用不銹材料制造，適于在潮濕的環(huán)境下工作。對介質清潔度不作嚴格要求。
閥位置有現場機械顯示和開關接點輸出。 　　
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
