صمامات كروية هوائية ثنائية الاتجاه من DELCO Valve 3PF ذات شفة
The DELCO DK66-3PF is a pneumatic flange ball valve with a two-way port configuration, compliant with GB standards by default, and also available in ANSI, JIS, DIN, or API 6D standards. It features a standard double-acting control mode, with an optional single-acting mode. The valve body is constructed from either 304 or 316 stainless steel and operates with an input air pressure range of 2.5 to 8 bar. It comes with a minimum 1/2 inch flanged connection and a default PTFE seat, ensuring resistance to almost all fluids. This valve is designed to handle higher operating pressures and temperatures.
الموديل: DK66-3PF
نطاق الحجم: 1/2″ to 4″
نطاق الضغط: 1.6 to 6.4 MPa
المادة: Stainless Steel 304/316, WCB

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.
