應(yīng)用范圍：
它廣泛應(yīng)用在航天、船舶重工、石油化工、工業(yè)爐窯、鍋爐、城市給排水、采暖空調(diào)、消防設(shè)備、干燥設(shè)備、食品醫(yī)療設(shè)備、清洗設(shè)備、景觀噴灌、水廠等管道系統(tǒng)中。

產(chǎn)品特點(diǎn)：
參照各系列電磁閥中的特點(diǎn)應(yīng)用，手動(dòng)柄開(kāi)關(guān)可以在電磁閥線圈無(wú)電或燒毀時(shí)，實(shí)現(xiàn)電磁閥打開(kāi)和關(guān)閉。

工作原理：
參照各系列電磁閥中的工作原理使用。

工作原理：
常閉型：當(dāng)電磁閥線圈不通電或燒壞，手動(dòng)可以打開(kāi)閥門。但手動(dòng)處于打開(kāi)狀態(tài)時(shí)閥不能自動(dòng)控制。
常開(kāi)型：當(dāng)電磁閥線圈不通電或燒壞，手動(dòng)可以關(guān)閉閥門。但手動(dòng)處于關(guān)閉狀態(tài)時(shí)閥不能自動(dòng)控制及線圈通電和斷電閥都不能打開(kāi)。

Applications:
It is widely used in aerospace, shipbuilding Heavy Industry, petrochemical, industrial furnaces, boilers, urban drainage, heating and air conditioning, fire fighting equipment, drying equipment, food and medical equipment, cleaning equipment, landscape irrigation, water and other piping systems.

Features:
The series solenoid valve in the light of the characteristics of application, the manual switch can handle without electricity in the solenoid valve coil or burned, the realization of the electromagnetic valve is opened and closed.

How it works:
Reference to the series of solenoid valves used in the works.

How it works:
Normally closed: When the solenoid valve coil is not energized or burned, you can manually open the valve. However, when the valve is turned on manually not automatically control.
Normally open: When the solenoid valve coil is not energized or burned, you can manually close the valve. However, when the valve is manually turned off and can not automatically control the valve coil is energized and power can not be opened.
