ASCO隔爆電磁閥,NF8327B011阿斯卡電磁閥
三通電磁閥
這些閥門有三個管接頭和兩個孔。當一個孔是打開的，另一個是關(guān)閉的，反之亦然。它們通常被用來交替施加壓力，從一個閥致動器或一個單一的作用缸的排氣壓力。這些閥門通常是關(guān)閉的，通常是開的或是通用的。
高流量，平衡閥芯的–1 / 4″
直接作用電磁閥的通用配置。可供交流或直流操作的黃銅或不銹鋼機構(gòu)。專為長壽命，高流量的低功率水平。

3-Way Solenoid Valves
These valves have three pipe connections and two orifices. When one orifice is open, the other is closed and vice versa. They are commonly used to alternately apply pressure to an exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal.
High Flow, Balanced Poppet – 1/4″
Direct acting solenoid valves in Universal configuration. Available either AC or DC operated in brass or stainless steel bodies. Designed for long life, high flow at minimum power levels.
