I. Product Overview
The DCV20 Manual Control Monoblock Directional Valve is a hydraulic component widely used in small-scale construction machinery (such as small loaders and hydraulic tools). It changes the flow direction of hydraulic oil through manual operation, thereby controlling the movement of actuators (such as cylinders and motors).
II. Key Features
1. Flow Range: The DCV20 typically has a flow range of ≤60L/min, making it suitable for small to medium flow hydraulic systems.
2. Pressure Rating: It has a rated pressure of ≥25MPa, enabling it to withstand high working pressures.
3. Control Method: Primarily manual directional control, offering simple and convenient operation for applications requiring basic mechanical control.
4. Structural Characteristics: Adopts a monoblock design, featuring a compact structure, easy installation, and space-saving benefits.
III. Application Areas
Due to its flow and pressure characteristics, the DCV20 Manual Control Monoblock Directional Valve is particularly suitable for the following fields:
1. Small-Scale Construction Machinery: Such as small loaders and hydraulic tools, used for controlling actions like digging, lifting, and unloading.
2. Other Hydraulic Systems: Hydraulic systems requiring small to medium flow rates and relatively high pressures, such as certain agricultural and forestry machinery.
IV. Selection and Maintenance Recommendations
1. Selection Recommendations:
• Choose the appropriate model based on the flow and pressure requirements of the hydraulic system. The DCV20 is suitable for systems with small to medium flow rates (≤60L/min) and relatively high pressures (≥25MPa).
• Consider the control method requirements. If manual control is needed in the system, the DCV20 is a suitable choice.
2. Maintenance Recommendations:
• Regularly inspect the seals of the valve to ensure there are no leaks.
• Clean any impurities inside the valve to prevent valve core sticking or wear.
• If the valve malfunctions, such as in the case of solenoid valve failure, first check the coil continuity (using a multimeter to measure resistance) and inspect for valve core sticking (cleaning out impurities).
