Stainless Steel Trieccentric pneumatic actuator Butterfly Valves
A three eccentric butterfly valve is characterized by the stem axis deviating from both the disc center and the body center simultaneously, with the rotation axis of the valve seat set at a specific angle to the channel axis of the valve body.
The DELCO DK67-WB-G Series butterfly valve features a triple offset design. This design offers the advantages of being lightweight, compact, and cost-effective, with low operating torque. It can effectively replace traditional gate valves, globe valves, and ball valves in most industrial applications.

DELCO Trieccentric Butterfly Valve with pneumatic actuator
The valve’s non-blind area design ensures minimal friction between the butterfly plate and valve seat. It has a thin layer valve seat structure with a replaceable seal pair and a balanced fixed structure. The body seat construction involves installing the valve seat directly on the body.

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.
