氣源處理器: 兼有過濾、減壓、潤滑功能,確保出口壓力穩定。提供兩件式組件用於過濾壓縮儀表空氣,以及三件式配置用於增加潤滑。
氣動電磁閥: 根據電壓訊號,透過磁化和消磁來調節氣動閥門的開啟和關閉,以引導氣體流動。對閥門操作進行精確控制,常用於管理氣源和迴路流量。
限位開關: 偵測閥門狀態並輸出開啟或關閉位置的訊號。在自動控制系統中至關重要,確認和執行後續程序,提供閥門聯鎖保護,並指示系統內的遠端警報。
閥門定位器: 對於氣動控制閥中閥門定位的精確控制至關重要,比較閥桿位移和控制器輸出訊號,相應地調整致動器輸出訊號。
手動裝置: 補充氣動執行器組件,方便 90° 開口的蝶閥和球閥的手動或氣動操作。確保閥門操作的多功能性和靈活性,允許根據需要進行手動和自動控制。
