JOUCOMATIC電磁閥ZBF24Q-10型自保持球閥主要是由閥體和驅(qū)動(dòng)機(jī)構(gòu)組成，是一種自保持閥門。在接到開(kāi)（關(guān)）閥信號(hào)后，驅(qū)動(dòng)機(jī)構(gòu)得電帶動(dòng)球閥閥芯轉(zhuǎn)動(dòng)，閥芯轉(zhuǎn)到位后電動(dòng)執(zhí)行機(jī)構(gòu)內(nèi)部自斷電，閥位機(jī)械指示指向相應(yīng)的閥位，閥位開(kāi)關(guān)輸出無(wú)源閥位信號(hào)。閥芯每轉(zhuǎn)90°，閥功能切換一次。ZBF24Q-10型自保持球閥采用球面密封結(jié)構(gòu)，無(wú)內(nèi)漏，比傳統(tǒng)滑閥結(jié)構(gòu)電磁換向閥密封更好。 　　
不存在滑閥無(wú)法克服的液壓卡緊力，因而對(duì)于長(zhǎng)時(shí)間不操作的油缸無(wú)需為防止液壓卡緊力而定時(shí)切換。 　　
驅(qū)動(dòng)機(jī)構(gòu)采用全套進(jìn)口產(chǎn)品，防護(hù)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(duì)介質(zhì)清潔度不作嚴(yán)格要求。
閥位置有現(xiàn)場(chǎng)機(jī)械顯示和開(kāi)關(guān)接點(diǎn)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
