Electro-hydraulic proportional pilot relief valve EDG is suitable for automation systems with many levels of pressure changes.
3. Electrohydraulic proportional pilot relief valve EDG is widely used in high-performance machines such as injection molding machines.
The electrohydraulic proportional pilot overflow valve EDG has the following models: EDG-01-B, EDG-01-C, EDG-01-H, EDG-01-B-T, EDG-01-C-T, and EDG-01-H-T.
Instructions for use: 1. Electro-hydraulic proportional pilot overflow valve EDG: As long as the exhaust port is ensured to be upward, the position of the exhaust port can be arbitrarily changed as needed.
2. The electro-hydraulic proportional pilot overflow valve EDG discharges air: To maintain stable control, it is necessary to exhaust all air and fill the iron core of the solenoid valve with oil. To exhaust air, gradually loosen the exhaust port at the proportional valve end. The position of the exhaust port can be changed so that air can be easily discharged from the valve. To change the position of the exhaust port, rotate the electromagnet connector until the exhaust port reaches the desired position.
3. Electro-hydraulic proportional pilot relief valve EDG oil return and drain pipes: The back pressure of the oil return and drain pipes directly affects the operating force of the main valve core of the low regulating pressure or flow regulating valve. Therefore, it is not allowed to connect the oil return pipe with other pipes, as it should be directly connected to the oil tank to keep the back pressure as low as possible. In addition, ensure that the ends of the return and drain pipes are immersed in the oil.
