Product Description:
Features and advantages of Rexroth hydraulic proportional directional valves include:
High control accuracy: Rexroth proportional directional valves adopt pilot structure design and are driven by proportional solenoids to achieve continuous and precise control of flow and direction in hydraulic systems.
Fast response speed: The valve core position is closed-loop controlled and is less affected by pressure fluctuations. It is suitable for precision machining equipment with a response time of ≤40 ms.
Good energy saving effect: The pilot control structure is adopted to reduce system energy consumption.
Wide application range: Suitable for various types of hydraulic systems to meet complex control requirements.
Strong environmental adaptability: Wide operating temperature range (-25℃ to +80℃) and suitable for different working environments.
Precautions for use include:
Correct installation: Ensure the correct installation of the proportional valve, including the cleanliness and tightness of the connecting pipes to prevent leakage or performance degradation.
Monitor key parameters: During operation, closely monitor the working status of the proportional valve, including key parameters such as input signal, output flow, temperature and pressure, to ensure that it operates within the normal range.
Regular maintenance: Regularly clean the valve body, check seals, and calibrate measuring equipment to ensure the continued stability and accuracy of the proportional valve.
Prevent pollution: The proportional valve has clear requirements for the contamination of the oil, which should usually be controlled within levels 7, 8, and 9 of NASl638 to prevent system failure.
Power domain problem: There is a power domain problem with the direct-acting electro-hydraulic proportional directional valve. It is necessary to ensure that it does not exceed its power domain to avoid the hydraulic force affecting the electromagnetic force and causing the valve opening to change.
