用途 User

該閥是作為管路的啟閉設備使用的，由一小電磁閥控制主閥的開關，可實現遠程和就地控制。

The valve is used as the opening and closing equipment of the pipeline, which controls the switch of the main valve by a small solenoid valve and can realize remote and local control.

特點 Characteristic

安裝使用方便，控制部分無復雜的電傳動機構，不易出故障，設定簡單。與傳統閥門比較有體積小，重量輕，功率小，維修簡單，使用方便，安全可靠的優點。

It is easy to install and easy to use. The control part has no complicated electric transmission mechanism. Compared with the traditional valve, it has the advantages of small volume, light weight, small power, simple maintenance, easy to use and safe and reliable.

原理 Principle

導閥為一電磁閥，當電磁閥打開時，膜片上腔壓力減小，主閥打開。電磁閥關閉，主閥也關閉。電磁閥分常開、常閉兩種。正常供貨狀態為常閉電磁閥。也可配置防爆型電磁閥。

The pilot valve is a solenoid valve. When the solenoid valve is opened, the cavity pressure decreases and the main valve opens. The solenoid valve is closed and the main valve is closed. Solenoid valve is normally open and closed. Normal supply status is normally closed solenoid valve. Explosion-proof solenoid valve can also be configured.
