Product details

1• Model: R901363282 DBEM20-71/350YG24K4V

2. Product Type:

• Proportional relief valve. This is a hydraulic valve that achieves continuous pressure adjustment of the system through electrical control signals, suitable for automated scenarios requiring high pressure control accuracy.

3. Technical Specifications and Characteristics:

• Size: 20 (some sources indicate that the size may be related to the component series, e.g., 7X represents component series 70-79).

• Pressure Rating: 350 bar, indicating the maximum working pressure the valve can withstand.

• Connection Type: Threaded connection for easy installation and removal.

• Electrical Control: Operates on 24V DC (G24), featuring low power consumption. The coil winding adopts a vacuum impregnation process to ensure reliable operation under frequent start-stop conditions.

• Control Method: Proportional solenoid control, enabling linear proportional pressure control by varying the input electrical signal (0-10V analog signal or 4-20mA current signal).

• Sealing Performance: The main body is equipped with a multi-stage sealing system that maintains stable sealing performance under a rated pressure of 31.5 MPa.

• Response Speed: The built-in pressure feedback mechanism allows for rapid response to system pressure changes, with a regulation time shorter than the industry average for similar products.

• Contamination Resistance: The unique contamination-resistant design enables the product to operate normally under NAS 1638 Class 9 oil cleanliness conditions. The dust-scraping structure installed at the valve spool's moving parts effectively extends the maintenance cycle.

4. Application Areas:

• Hydraulic control systems for construction machinery.

• Pressure-holding circuits for forging presses.

• Clamping systems for injection molding machines, etc.

5. Installation and Maintenance:

• The compact pipe-mounted installation structure facilitates system integration. The 24° conical seal used at the oil inlet and outlet ports can accommodate various pipeline connection requirements.

• It is recommended that users regularly inspect the filter status of the pilot control oil circuit and maintain the oil temperature within the operating range of -20°C to 80°C to ensure long-term stable operation of the equipment.
