Product Specification

Product Description:

‌The valve amplifier features of the solenoid valve proportional valve mainly include the following points:

‌Precise control‌: The proportional amplifier can accurately convert electrical signals into hydraulic power to achieve fine control of the hydraulic system. Unlike traditional switch-type solenoids, proportional solenoids can achieve continuous control, allowing fine-tuning to adapt to different control needs‌.

‌Continuous adjustment‌: Proportional hydraulic valves include proportional pressure valves, proportional flow valves, etc., which can receive electrical signals and make continuous adjustments. This continuous adjustment capability enables the system to accurately control flow and pressure as needed, and is widely used in industrial machinery, construction machinery, cranes and other equipment‌.

‌Energy-saving‌: By accurately controlling the pressure and flow of the proportional valve in the hydraulic system, precise adjustment of mechanical movement can be achieved, thereby improving the working efficiency and operating accuracy of the equipment. In addition, this control method can effectively save energy and optimize system performance‌.

‌Precautions when using proportional valve amplifiers‌ include:

‌Shielded cables‌: All cables leading to the outside must be completely shielded to prevent electromagnetic interference. When using controllers and adjustment modules, there must be no strong electromagnetic interference sources nearby‌.

‌Wiring specification‌: Analog signal cables must be shielded, and other cables must also be shielded when there is a strong interference source and the cable length is greater than 3 meters. When wiring, the EMC (electromagnetic compatibility) design specification should be followed, and a star grounding wiring scheme should be used.

‌Power supply requirements‌: The power supply should be provided by a voltage-stabilized power supply unit, such as a PELV system that complies with the IEC364-4-4 safety low voltage specification. A low-resistance voltage-stabilized power supply helps to suppress external voltage interference and improve the signal quality of high-resolution sensors.

‌Pollution control‌: The proportional valve has strict requirements on the contamination of the oil, usually requiring NASl638 level 7-9. The oil must be filtered with a filter with a filtration accuracy of less than 20 microns before entering the proportional valve, and the oil tank must be sealed and an air filter must be added.

‌Installation and commissioning‌: Before installing the proportional valve, you should carefully read the manufacturer's product samples and other technical information to understand the use and installation conditions and precautions in detail. When installing, be careful not to damage or miss the seals, the connecting plate should be flat and smooth, and the bolts should be fixed with uniform force. The amplifier is used in conjunction with the proportional valve, and the wiring should be careful not to connect by mistake.
