I. Product Overview
TheCDB15 Hydraulic Control Valveis a hydraulic component that integrates a flow divider valve and a multi-way directional control valve into a single unit. It is designed for applications where the vehicle's steering system and cylinder operating system share a single oil pump. This design simplifies the system structure, facilitating easier installation and maintenance.

II. Product Features
1. Compact Structure:
• The CDB15 features a modular (slice-type) design, allowing for flexible combinations of 1 to 10 sections to meet diverse user requirements.
2. Comprehensive Functionality:
• It offers multiple functions, including flow division, directional control, and pressure stabilization, ensuring stable operation of the hydraulic system.
3. Safe and Reliable:
• Equipped with a self-locking valve stem to prevent vibrations caused by negative pressure inside the tilt cylinder.
• Locks the tilt cylinder when the engine is off, avoiding accidental movements and ensuring operational safety.
4. Easy Maintenance:
• Its modular design simplifies repairs and reduces maintenance costs.

V. Working Principle
The CDB15 Hydraulic Control Valve achieves various hydraulic functions by moving the valve spool to alter oil path connections and flow directions. For example:
• In directional control valve sections, spool movement controls cylinder extension/retraction and steering system actions.
• In flow divider sections, adjustable flow ratios ensure stable oil supply to both the steering and working systems.
