Stainless Steel Wafer Type Short Thin Pneumatic Ball Valves
The pneumatic actuated thin wafer type ball valves is a modern version of pneumatic ball valves. Developed with Italian technology adapted for local requirements, this valve features an ultra-short flange distance. It comes in various ball core channel shapes, including rectangular, V-shaped, and O-shaped. Known for its compact design, small size, light weight, and ease of installation, this valve is ideal for use in petroleum, chemical, metallurgical, power, and light industries. It can automatically control or stop the flow of oil, water, gas, pulp, or fibrous fluids.
Model: DK66-BV
Size Range: 1/2″ to 4″
Pressure Range: 1.6MPa to 6.4 MPa

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.
