Key Features of the DBETA Proportional Pressure Relief Valve by Bosch Rexroth

 

The DBETA series boasts a range of impressive features, making it stand out in the world of hydraulic pressure control:

         

 

Nominal Pressure: With a nominal pressure range from 50-500 bar, the DBETA valve is engineered to handle a wide range of hydraulic systems.

Maximum Flow: Achieving a maximum flow of 5 Lpm, which is great for piloting pumps and control valves. 

Integrated Pressure Sensor, Controller, and Amplifier: The DBETA comes equipped with onboard electronics, including an integral pressure sensor, controller, and amplifier, providing closed-loop pressure control. 

 

Benefits of the DBETA Proportional Pressure Relief Valve by Bosch Rexroth

Configurable Pressure Settings

The DBETA Proportional Pressure Relief Valve is known for its configurable pressure settings. This makes it adaptable to various applications and hydraulic systems. The valve can be set up to the exact pressure needed for the system it is controlling, ensuring efficient performance. The ability to customize settings also means that you can tailor the valve to your specific hydraulic system needs.

The DBETA series offers versatile pressure settings to cater to various applications:

7250 psi (500 bar): This configuration provides a high-pressure option for demanding hydraulic systems.

725 psi (50 bar): Ideal for applications requiring lower pressure relief.

1450 psi (100 bar): A mid-range pressure option suitable for various scenarios.

2900 psi (200 bar): Offering flexibility in hydraulic pressure control.

5075 psi (350 bar): Another high-pressure configuration to suit your system's requirements.

 

Precise Control with Embedded Electronics

The DBETA valves are meticulously crafted for precise and regulated hydraulic pressure control in closed-loop systems. It seamlessly responds to electrical command signals, be it voltage or amperage, and showcases an embedded pressure sensor/transducer. Boasting hysteresis measurements of less than 1% and linearity values within +/- 1% of the maximum pressure setting. 

Precision really is the cornerstone of hydraulic pressure control systems, and the DBETA series has been engineered with utmost precision and accuracy to ensure flawless functionality. The integrated electronics within the valve offer exact control, maintaining hydraulic pressure within the desired limits. This not only minimizes wear and tear on the hydraulic system components but also enhances the system's longevity.


Operating Modes

Similar to their predecessor, the DBETE series, the DBETA valves can operate in an open loop, eliminating the need for a pressure sensor/transducer. Integrated into the package is a dip switch panel that allows you to select the pressure control mode, making it a versatile choice for various modes of operation.


Unmatched Response Time

The DBETA series also boasts an unmatched response time. The valve is designed to react to pressure variations quickly, ensuring that the pressure is always within the configured range. This fast response time is essential in reducing the risk of system damage due to pressure surges.

 

Durability and Reliability

Hydraulic pressure control systems are prone to wear and tear due to the high pressure they operate under. The DBETA series is manufactured with high-quality materials to ensure durability and resistance to corrosion. The valve is also designed to handle repeated use, ensuring that the system can run for longer intervals without maintenance interventions.

 

Customizable for Your Application

The DBETA series can be customized to suit your specific application needs. Additionally, the valve series offers different sizes and pressure ranges, ensuring that you can find the perfect valve for your hydraulic system. Although a very versatile solution, it is ideally suited for hydraulic pump control systems with remote pressure control arrangements. Its adaptability and precise pressure control capabilities make it an excellent choice for a wide range of applications in the hydraulic industry.

Product Update - Now Including Bluetooth Connection 

With its subplate mounting design, the Bosch Rexroth DBETA Relief Valve series conforms to the NG6 (D03) mounting pattern. This versatile valve not only allows for pressure control but also offers the option for integrated digital electronics (OBED). It meets the CE standards outlined in the EMC Directive 2014/30/EU and ensures precise control with its linear command value pressure characteristic curve. The valve can be equipped with both integrated and external pressure sensors, allowing for adjustable pressure in various applications. It also provides multiple interface options, including digital (IO-Link, Bluetooth), and analog interfaces. With the added convenience of Bluetooth functionality, users can easily analyze and adjust the valve's settings using a dedicated app.

 

In Summary... 

Hydraulic pressure control systems are complex systems that require the right components to function best. The Bosch Rexroth DBETA Proportional Pressure Relief Valve is a reliable and efficient solution for hydraulic pressure control. The valve offers configurable pressure settings, precise control, unmatched response time, durability, and reliability, and is customizable for specific applications.

If you are in search of a pressure relief valve that can revolutionize your hydraulic control systems, the Bosch Rexroth DBETA series is definitely worth your consideration.
