该阀在1口和3口均有压力输入，其中较高的一端从2口输出，较低的一端关闭。其优点是适于高压、几乎零泄漏，体积小，结构紧凑。

The valve has pressure input at both ports one and three,The higher pressure end is connected to port tow,The lower pressure end is shutting,It’s advantages are suitable for high pressure,almost zero leakage, small volume,and compact construction.
