? 元件號中給出的響應值是制造廠在2 L/min流量下設定的。
? 元件號中給出的最大允許流量針對回油（油口?T”）管中無背
壓的工況成立。
? 拆下安全閥的印封，DGRL的認可無效！
? 必須考慮壓力元件指南和樣本AD2000-A2的要求！
? 推荐通過把插件連接在閥體/塊體上，並且加印封（孔在插
件的六角中），來避免非授權地從閥體/塊體上拆卸經過設
計認証的插裝閥。
注意！
由於在回油（油口?T”）管中的背壓值，系統壓力隨著流量加大
而提高。（必須考慮樣本AD2000-A2中的要點6.3）
由於流量的關係，要保証系統壓力不能高於設定響應壓力的
10%，允許的流量必須相對於回油（油口?T”）管中的背壓而減
小（見12-14頁的圖）。
