DELCO 法蘭氣動圓頂閥
DELCO Pneumatic dome valve adopts top-mounted structure, which reduces the connecting bolts of the valve body itself under the conditions of high pressure and large caliber, and enhances the reliability of the valve and overcomes the influence of the self-weight of the system on the normal work of the valve.
型號： 氣動圓頂閥
Size range: DN15-DN150
材質： carbon steel, stainless steel
Flanged Pneumatic Operated Dome Valve
Easy Installation and Maintenance: Standardized products and parts can be directly installed on silos and easily replaced for maintenance purposes.
Low Torque Design: The dome valve is sealed and closed using an inflatable gasket inflated by supplied air, resulting in very low torque.
Controlled Air Injection and Ventilation: Inflatable gasket and solenoid valve control air injection and ventilation to minimize friction between the gasket and the spherical cap.
High Sealing Efficiency: Simultaneous utilization of gasket and air ensures high sealing performance.

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。
