P40-DKL Solenoid-Operated 4-Way Monoblock Directional Control Valve
A high-performance, compact hydraulic directional control valve designed for precise fluid control in industrial and mobile hydraulic systems.
------
Core Functions
1. Directional Control
• Driven by a solenoid actuator, the valve spool shifts to redirect hydraulic fluid flow, controlling the movement direction of actuators (e.g., hydraulic cylinders, motors).
• Four working ports (P, A, B, T) support multi-circuit independent control for complex hydraulic systems.
2. Flow Regulation
• Rated flow rate of40 L/min, suitable for small-to-medium hydraulic systems.
• Adjustable spool opening or integration with throttle valves enables fine flow control.
3. Pressure Management
• Maximum operating pressure of250 bar, ideal for high-pressure hydraulic applications.
• Built-in pressure compensation ensures stable system performance.
4. Fluid Compatibility
• Operates with viscosity ranges of15–75 mm²/s, compatible with various hydraulic oils (mineral-based, synthetic).
• Temperature tolerance of-40°C to +80°C, suitable for extreme environments.

Structural Design
1. Monoblock Construction
• Single-piece valve body minimizes leakage points and enhances reliability.
• Compact design saves installation space and simplifies integration into hydraulic systems.
2. Modular Expandability
• Supports multi-section stacking for functional expansion (e.g., pressure control, flow control).
• Standardized interfaces ensure compatibility with mainstream hydraulic systems.
3. Durability
• High-strength cast iron or stainless steel valve body resists impact and corrosion.
• Precision-machined spool-and-sleeve pairing ensures long-term jam-free operation.
