DBEM Series
Hydraulic systems are widely used in industrial and mobile applications due to their high power density, precision, and control flexibility. These systems use hydraulic pumps, motors, and valves to convert mechanical power into fluid power and vice versa. Among these components, valves play a crucial role in controlling the fluid flow and pressure in the system. They regulate the direction, flow rate, and pressure of the hydraulic fluid, allowing the system to perform various functions such as lifting, pushing, rotating, or stopping loads.
To meet the ever-growing demand for high-performance and energy-efficient hydraulic systems, Bosch Rexroth, a global leader in drive and control technologies, offers a comprehensive range of hydraulic valves, including the DBEM series of proportional pressure control valves.
The DBEM series is a modular and flexible valve system that combines high-precision proportional control with fast response times, low hysteresis, and high dynamic range. These valves are designed to control the pressure in hydraulic systems with closed-loop or open-loop control, depending on the application requirements. They can handle maximum pressure ratings of up to 315 bar and flow rates of up to 300 l/min, making them suitable for a wide range of industrial and mobile applications, including machine tools, plastics processing, metal forming, presses, cranes, excavators, and agricultural machinery.
The DBEM series includes three types of valves: DBEME, DBEMC, and DBEMR. The DBEME valves are electro-hydraulic pressure control valves with digital onboard electronics that allow for easy setup and parameterization via a PC or PLC. They come in two versions: the DBEME 10 with a maximum flow rate of 40 l/min and the DBEME 30 with a maximum flow rate of 150 l/min. The DBEMC valves are hydraulic pressure control valves with onboard electronics that enable remote parameterization and monitoring via a CAN bus or Ethernet interface. They come in two versions: the DBEMC 10 with a maximum flow rate of 40 l/min and the DBEMC 30 with a maximum flow rate of 300 l/min. The DBEMR valves are hydraulic pressure control valves with analog electronics that provide proportional control via a 0-10 V or 4-20 mA signal. They come in four versions: the DBEMR 10 with a maximum flow rate of 40 l/min, the DBEMR 20 with a maximum flow rate of 100 l/min, the DBEMR 30 with a maximum flow rate of 150 l/min, and the DBEMR 40 with a maximum flow rate of 300 l/min.
The DBEM series offers several benefits for hydraulic system designers, operators, and maintenance personnel. First, they provide precise and stable pressure control, which ensures the safety and reliability of the system and improves the quality of the output. Second, they allow for energy-efficient operation by reducing pressure drops and minimizing fluid leaks, which saves energy and reduces operating costs. Third, they enable flexible and scalable system design by offering various control options and easy integration with other components. Fourth, they facilitate troubleshooting and maintenance by providing diagnostic functions, such as fault codes, status indicators, and log files, that help identify and resolve issues quickly.
