DELCO Stainless Steel Vacuum Pneumatic Butterfly Valves
Introducing the DELCO pneumatic vacuum butterfly valves, compatible with GB, ANSI, JIS, and DIN standards.
This valve operates in a double acting standard control mode, with an optional single acting configuration. It is constructed from 304 or 316 stainless steel and is available in sizes ranging from DN50 to DN400. The valve can handle working temperatures from -30℃ to 80℃, and medium temperatures from -30℃ to 150℃.
型號: DK67-GID
尺寸範圍: 2″-24″
壓力範圍: 0.1MPa~0.6MPa
材質: 不銹鋼 304/316
DELCO Sanitary Butterfly Valve with Pneumatic Actuator
Suitable for various media such as water, oil, air, and gas, the valve delivers nearly linear flow characteristics, ensuring excellent regulation performance. The connection between the butterfly plate and the valve stem uses a pinless design, eliminating potential internal leakage points. Additionally, the seal is replaceable and reliable, providing effective two-way sealing for enhanced durability and 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。
