帶有伺服隔膜和強制提升裝置的先導式直通閥有兩種類型，即在無流量時關閉或在無流量時打開。當作用方式 A 為關閉狀態時，芯體會在彈簧力的作用下將先導式孔眼關閉。經由一個隔膜節流孔，在隔膜上方形成介質壓力，進而關閉閥門。接通時，芯體先打開先導式孔眼。隔膜上方的關閉壓力被卸除，且閥門由介質壓力打開。

實物圖如下：

There are two types of pilot through valves with servo diaphragms and forced lifting devices, which are closed without flow or open when no flow occurs. When the action mode A is closed, the core experiences the closing of the pilot hole under the action of the spring force. Through a diaphragm orifice, the medium pressure is formed above the diaphragm, and then the valve is closed. When the switch is connected, the core body opens the pilot hole first. The closing pressure above the diaphragm is removable, and the valve is opened by the medium pressure.
