Product details

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.
