DELCO Lug Style Spring Return Air Actuated Butterfly Valve
The LT type, also known as the single plate butterfly valve or lug type butterfly valve, is a straightforward regulating valve design. It’s particularly suitable for low-pressure pipeline applications where the closing element, typically a disk or butterfly plate, rotates around the valve shaft to control the flow by opening and closing.
This type of valve finds utility across various fluid types, including air, water, steam, corrosive media, mud, oil products, and liquid metals. In pipelines, its primary function is to cut off or throttle the flow. The butterfly valve operates with a disc-shaped butterfly plate, pivoting around its axis within the valve body to regulate the flow or completely shut it off.

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。
