To provide a solenoid operated valve having a structure that can be used even if a fluid flowing through the solenoid operated valve has corrosiveness to a bond or an adhesive which fixes an elastomer material to a valve member.SOLUTION: A solenoid operated modular valve 20 includes a valve body 22, a valve member 24 slidingly received in the valve body 22, and a solenoid 26 that moves the valve member 24 between an open position and a closed position. The valve body 22 has an end face 30, a side face 32, and an inner bore 34. An outlet port 36 in the end face 30 is disposed in fluid communication with the inner bore 34. An inlet port 38 in the side face 32 is disposed in fluid communication with the inner bore 34. The valve body 22 includes an O-ring valve seat 102 that is positioned longitudinally between the inner bore 34 and the outlet port 36. The valve member 24 includes a tapered end 108 that has a frustoconical shape and a valve member abutment surface 110. The valve member abutment surface 110 contacts the O-ring valve seat 102 when the valve member 24 is in the closed position.SELECTED DRAWING: Figure 2 【課題】電磁弁を流れる流体が、エラストマー材料をバルブ部材に固定する接合剤または接着剤に対して腐食性がある場合でも使用できる構成の電磁弁を提供する。【解決手段】電磁モジュラーバルブ２０は、バルブ本体２２と、バルブ本体２２に摺動可能に収容されるバルブ部材２４と、開位置と閉位置の間を移動させるソレノイド２６とを備える。バルブ本体２２は、端面３０、側面３２および内部孔３４を有する。端面３０の流出口３６は、内部孔３４と流体連通して設けられる。側面３２の流入口３８は、内部孔３４と流体連通して設けられる。バルブ本体２２は、長手方向において内部孔３４と流出口３６の間に配置されるＯリング弁座１０２を備える。バルブ部材２４は、円錐台形状のテーパー端部１０８、およびバルブ部材当接面１１０を有する。バルブ部材当接面１１０は、バルブ部材２４が閉位置にある時、Ｏリング弁座１０２と当接する。【選択図】図２
