德國寶德burkert0407型號 0407 是一種帶有伺服活塞和強制提升裝置的先導(dǎo)式電磁閥，適合溫度不超過 +180 °C 的介質(zhì)。閥門在 0 bar 時即可打開，無需差壓作用，在無流量時，閥門會在自身介質(zhì)壓力及彈簧力的作用下關(guān)閉。valve with servo-piston and forced valve lifting, and is suitable for media temperatures up to+180°C. The valve opens without differential pressure from zero bar, and is closed by its own media pressure and spring force without power supply實圖如下

Burkert0407電磁閥維護故障排除
安全說明
警告！
Burkert0407電磁閥保養(yǎng)不當(dāng)受傷的危險！
•維修時可以進行的唯一授權(quán)技術(shù)，并與相應(yīng)的工具！從系統(tǒng)的錯誤動作和非受控重啟受傷的危險！
•無意激活安全系統(tǒng)。
•以下維護，保證了控制的重啟
安裝線圈
警告！
從設(shè)備的高壓受傷的危險！
•之前松開管道和閥門，關(guān)閉壓力和排氣的行。如果線圈和身體的保護導(dǎo)體接觸缺失，有觸電的危險！
•檢查保護導(dǎo)體接觸安裝線圈后。逃離中！當(dāng)粘螺母被松開，介質(zhì)可以逸出。
•不要擰緊螺母堅持任何進一步。
電擊！
如果線圈和身體的保護導(dǎo)體接觸缺失，有觸電的危險！
•檢查保護導(dǎo)體接觸安裝線圈后。危險以免發(fā)生電擊，如果線圈安裝不正確！
•安裝期間確保線圈牢固地坐落在主體罩，使線圈的保護導(dǎo)體連接被連接到閥體
Burkert0407電磁閥檢查步驟：
→線圈體連接到核心引導(dǎo)管。
→擰上線圈螺母。觀察扭矩。
→檢查保護導(dǎo)線。
注意！
The device will be damaged if the wrong use of tools! Always use the wrench to tighten the nut. If other tools are used (e.g., forceps), the device may be damaged.
step:
→ coil body is connected to the core guide tube.
→ Tighten the nuts on the coil. Observation of torque.
→ Check the protective conductor.
note!
The device will be damaged if the wrong use of tools! Always use the wrench to tighten the nut. If other tools are used (e.g., forceps), the device may be damaged.
Burkert0407 solenoid valve failure
If a failure occurs, check:
→ equipment in accordance with instructions for installation,
→ electrical and fluid connections are correct,
→ device is not damaged,
→ all the screws are tightened,
→ voltage and pressure has been turned on,
→ pipes are clean.
Burkert0407 Solenoid valves do not switch Possible causes:
• short circuit or coil interrupted,
• core or core area dirty
• outside the permissible pressure range of the pressure. The valve is not closed Possible causes:
• internal valve space dirty.
• In the hole to prevent small control piston.
