Product details

Introduction to DH-9 Hydraulic Joystick Control Valve:

I. Functional Features

The DH-9 hydraulic joystick control valve serves as a core control component in hydraulic systems, primarily used for hydraulic power distribution and directional control in construction machinery, agricultural equipment, or industrial facilities. Its typical functions include:

1. Multi-channel Hydraulic Power Distribution: Enables a single joystick to independently or simultaneously control multiple hydraulic actuators (e.g., hydraulic cylinders, motors), enhancing operational efficiency.

2. Directional Control: Precisely manages the flow direction of hydraulic oil to start, stop, reverse, or adjust the speed of actuators.

3. Pressure Regulation and Safety Protection: Integrates relief or safety valve functions to prevent system overload and ensure safe equipment operation.

4. Modular Design: Some models feature a modular structure for easy maintenance and functional expansion, adapting to diverse working conditions.

II. Application Scenarios

The DH-9 hydraulic joystick control valve is widely applied in the following fields:

1. Construction Machinery: Used in hydraulic systems of excavators, loaders, and bulldozers to control the movements of buckets, booms, tracks, and other actuators.

2. Agricultural Machinery: Employed in combine harvesters, tractors, etc., to achieve hydraulic control of functions such as header lifting, steering, and power take-off.

3. Industrial Equipment: Utilized in automated machinery like injection molding machines and die-casting machines for precise hydraulic control of mold opening/closing and ejection mechanisms.

III. Technical Parameters (Examples)

【表格】

Parameter Category Typical Value Description

Rated Pressure 20-35 MPa Depends on specific model and design standards

Flow Range 40-100 L/min Meets speed requirements of different actuators

Control Method Manual/Pilot-operated Direct manual operation or remote control via pilot valves

Port Size G1/2" - G1" Compatible with hydraulic systems of varying pipe diameters

Operating Temperature -20°C to +80°C Ensures stable operation in harsh environments

Protection Grade IP65 or higher Dustproof and waterproof, extending service life

IV. Selection Recommendations

1. Clarify Operational Requirements: Choose a model with rated pressure and flow matching the equipment type, load size, and action frequency.

2. Prioritize Control Precision: For scenarios demanding smooth operation (e.g., precision machining equipment), opt for models with proportional control functions.

3. Consider Environmental Adaptability: Confirm valve material and seal performance when used in high/low-temperature or corrosive environments.

4. Evaluate Maintenance Convenience: Prioritize modular, easily disassembled models to reduce long-term maintenance costs.
