2871-A-01,0-FF-MS-GM81-024/DC-05 2871-2/2常閉型電磁閥-DN1-FKM密封-黃銅閥體-G1/8"-024/DC-5
類型 2871 - 直動式二通標準比例電磁閥
類型描述
直動式電磁控制閥 2871 型，在控制回路中用作調(diào)節(jié)單元。由于采用彈性閥座密封件，閥門密閉性好（內(nèi)置關(guān)斷功能），能達到與通徑相當?shù)念~定壓力。閥門的柱塞無摩擦力，因而具有的調(diào)節(jié)性能。該閥尤其適合于控制需求較高的應用（控制范圍廣，干燥氣體等）。
（1）控制范圍廣
（2）快速響應
（3）緊湊型結(jié)構(gòu)
（4）通徑 DN 0.05 - 2.0 mm
（5）連接接口1/8”或底板連接
