Product details

TheYZFB10 Flying Boom Changeover Valveis a specialized valve designed to control the fluid path switching in flying boom systems, enabling functions such as boom extension, retraction, or directional adjustment. Below is an overview of its technical features, applications, and operating principles:

------

I. Technical Features

1. Structural Components

• Valve Body: Constructed from high-strength alloy materials (e.g., stainless steel or aerospace aluminum alloy) to withstand high-pressure, high-frequency switching conditions, ensuring long-term corrosion resistance and structural stability.

• Switching Mechanism: Equipped with precision gear sets or hydraulic drive modules for rapid response via electric/pneumatic signals, with switching times typically ≤0.5 seconds to meet dynamic control requirements of flying booms.

• Sealing System: Features a dual-stage sealing design (e.g., metal hard seal + rubber soft seal) with a pressure rating of up to PN40 (4 MPa), preventing fluid leakage and ensuring operational safety.

2. Performance Parameters

• Nominal Diameter Range: DN25–DN100, accommodating varying flow demands across different boom system scales.

• Temperature Range: -40°C to +120°C, suitable for extreme environments (e.g., high-altitude low-temperature or high-temperature operations).

• Control Modes: Supports manual, electric, or pneumatic control, with integration capabilities into automated systems for remote operation.

II. Applications

1. Aerial Work Platforms

• Used to control hydraulic oil path switching in flying booms, enabling lifting, rotation, or telescoping of boom arms for enhanced operational flexibility.

• Typical use cases: Fire truck ladders, streetlight maintenance vehicles, wind turbine blade installation platforms.

2. Aviation Refueling Equipment

• In rigid air-to-air refueling systems (e.g., "boom-type" refueling devices), the valve directs fuel flow to ensure precise alignment between the refueling boom and receiver aircraft.

• Advantage: Rapid switching reduces docking time, improving refueling efficiency and safety.

3. Industrial Lifting Machinery

• Applied in crane luffing mechanisms to adjust hydraulic cylinder pressure for precise control of jib angles.

------

III. Operating Principle

1. Signal Input

• Receives electrical signals (e.g., 24V DC) or pneumatic signals (e.g., 0.6 MPa) from control panels or automated systems.

2. Drive Actuation

• Electric Type: A motor drives gear sets to rotate, moving the valve spool to the target flow path.

• Pneumatic Type: Compressed air pushes a piston to drive valve spool positioning.

3. Flow Path Switching

• Upon spool movement to the designated position, fluid switches from the original flow path to the target path (e.g., from "retraction" to "extension").

• Seal rings ensure leak-free switching, maintaining system pressure stability.

4. Status Feedback

• Some models incorporate position sensors to provide real-time spool position feedback to the control system, enabling closed-loop control.
