I. Product Overview
Rexroth, a wholly-owned subsidiary of the German Bosch Group, is a leading supplier in the industrial technology market. Its original new relief valves are crucial components in industrial hydraulic systems, used to control system pressure and prevent system overload. These relief valves adopt advanced design and manufacturing processes to ensure high performance, high reliability, and long service life.
II. Product Features
1. High-Precision Control: Rexroth relief valves have the ability to accurately control system pressure, ensuring stability and safety during the operation of hydraulic systems.
2. Fast Dynamic Response: The valve spool movement is controlled by a proportional solenoid, which can quickly respond to changes in input current, thereby achieving rapid adjustment of system pressure.
3. Compact Structure: Rexroth relief valves adopt a compact structural design, occupying little space and facilitating installation and maintenance.
4. Strong Corrosion Resistance: The valve body is made of high-quality materials, exhibiting good corrosion resistance and wear resistance, capable of operating stably in harsh working environments for a long time.
III. Product Models and Specifications
Rexroth original new relief valves offer a variety of models and specifications to meet the needs of different customers. Among them, R930077359, R930054929, and R931002539 are common models. Detailed information about specific models and specifications may vary due to product batches and manufacturing dates. Therefore, when selecting and purchasing, please refer to the latest product catalog or contact the manufacturer for accurate information.
IV. Application Fields
Rexroth original new relief valves are widely used in various industrial hydraulic systems, such as machine tools, plastic machinery, food and packaging machinery, metallurgy, and the automotive industry. They play an important role in controlling system pressure, protecting hydraulic components, and extending equipment service life in these fields.
V. Maintenance and Servicing
To ensure the long-term stable operation of Rexroth original new relief valves, regular maintenance and servicing are required. This includes checking the wear of the valve spool and valve seat, cleaning the valve body, and replacing damaged seals. Additionally, the following points should be noted:
1. Regularly check if the system pressure is stable. If there are abnormal fluctuations, promptly identify the cause and address it.
2. Avoid long-term overload operation to prevent damage to the valve body and valve spool.
3. During use, maintain system cleanliness and avoid impurities and contaminants entering the valve body interior.
VI.Main Product Series and Models
Rexroth relief valves encompass various types and series, catering to the pressure control needs of different hydraulic systems:
• DBDS Series: Cartridge-style relief valves, such asDBDS10K1C/315, feature a compact design supporting threaded connections or manifold baseplate installations. With a rated pressure of 315 bar, they are suitable for high-pressure industrial machinery and mobile equipment.
• DBETE Series: Proportional relief valves, likeDBETE-6X315G24K31A1M, adjust pressure proportionally to the input current, enabling intelligent control. They are ideal for high-precision industrial automation systems.
• DBW Series: Pilot-operated relief valves, such asDBW20B2-5X/100-6EW230, are suitable for large-flow systems. They integrate pressure regulation and fault warning functions, commonly found in construction machinery and heavy-duty equipment.
• DBD Series: Direct-acting relief valves, likeDB10-1-44/200 W65, use cast iron material and flange mountings, suitable for high-temperature and high-pressure environments with pressure ratings up to 630 bar.
