Product Introduction
用途 User
该阀是作为管路的启闭设备使用的，由一小电磁阀控制主阀的开关，可实现远程和就地控制。
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.
特点 Characteristic
安装使用方便，控制部分无复杂的电传动机构，不易出故障，设定简单。与传统阀门比较有体积小，重量轻，功率小，维修简单，使用方便，安全可靠的优点。
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
导阀为一电磁阀，当电磁阀打开时，膜片上腔压力减小，主阀打开。电磁阀关闭，主阀也关闭。电磁阀分常开、常闭两种。正常供货状态为常闭电磁阀。也可配置防爆型电磁阀。
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.
