常閉截止換向閥，三通截止閥K23JD-08
特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。
原理：通電時，電磁力把先導孔打開，上腔室壓力迅速下降，在關閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把先導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。
電磁閥從閥結構和材料上的不同與原理上的區別，分為六個分支小類：直動膜片結構、分步直動膜片結構、先導膜片結構、直動活塞結構、分步直動活塞結構、先導活塞結構。
AirTac pilot solenoid valve:
Features: the upper limit of the fluid pressure range is higher, can be arbitrarily installed (to be customized) but must meet the conditions of fluid pressure difference.
Principle: power, the electromagnetic force to open the pilot hole, the chamber pressure to drop rapidly in close formation around the lower parts of high pressure, fluid pressure to promote the closure of parts moving up, the valve open; power, the spring force of the pilot hole closed, entrance pressure chamber through the bypass hole quickly formed under low. The high pressure around the valve off, fluid pressure to promote the closure of parts moving down, close the valve.
Solenoid valve from different principle and valve structure and materials on, divided into six branch categories: diaphragm structure, step by step direct acting diaphragm structure, pilot diaphragm structure, direct acting piston structure, direct acting piston structure step by step, the pilot piston direct drive structure.
