DELCO Sanitary Butterfly Valve with Pneumatic Actuator

The DELCO pneumatic vacuum butterfly valve features a simple and compact structure, providing low operating torque for efficient performance. It offers two actuator types: spring return (single acting) and double acting, with a 90° rotary motion. The valve adheres to multiple standards, including GB, ANSI, JIS, and DIN, and supports both flange end and wafer connections.

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.

Technical Parameters of Valve Actuator

Double acting	Air to open, air to close, air supplier failure to keep the current position
Single acting N/C	Air to open, interrupt air to close, air failure to close
Single acting N/O	Air to close, interrupt air to open, air failure to open
Optional accessory	Reversing solenoid valve, limit switch box, air filter reducing valve, positioner, handle manual, lock up valve.

Pneumatic Actuator

Actuator

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.
