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.

Air source processor: Combines filtering, pressure reduction, and lubrication functions, ensuring stable outlet pressure. Available in two-piece assemblies for filtering compressed instrument air and three-piece configurations for added lubrication.
Pneumatic solenoid valve: Regulates the opening and closing of pneumatic valves by magnetizing and demagnetizing to direct gas flow based on voltage signals. Offers precise control over valve operations, commonly used for managing gas source and circuit flow.
Limit switch: Detects valve status and outputs signals for open or closed positions. Critical in automatic control systems, confirming and executing subsequent programs, providing valve interlock protection, and indicating remote alarms within the system.
Valve positioner: Crucial for precise control over valve positioning in pneumatic control valves, comparing valve stem displacement and controller output signals, adjusting the actuator output signal accordingly.
Manual device: Complements pneumatic actuator assemblies, facilitating manual or pneumatic operation for butterfly and ball valves with a 90° opening. Ensures versatility and flexibility in valve operation, allowing for manual and automated control as needed.
