Rexroth Relief Valve DBDH6K18/50 Silver Cast Iron High Reliability Precise Pressure Control Energy Saving

Description:

The Rexroth Relief Valve DBDH6K18/50 is a high-performance hydraulic pressure relief valve manufactured by Bosch Rexroth of Germany. This relief valve is an essential safety and control component in hydraulic systems, primarily used to limit the maximum operating pressure in the hydraulic system, prevent system overload, and protect hydraulic components from damage. It also serves as a constant pressure source, providing a stable oil supply pressure. The Rexroth Relief Valve DBDH6K18/50 utilizes a pilot-operated design, operating by controlling the opening and closing of the main valve spool via a pilot valve. When the hydraulic system pressure reaches the set value, the pilot valve opens, allowing hydraulic oil to flow through the pilot valve into the control chamber of the main valve spool, pushing the main valve spool open and draining excess hydraulic oil back to the tank, maintaining stable system pressure. This design enables the relief valve to achieve high response speed and precise pressure control capabilities.

Applications:

Industrial Hydraulic Systems: The Rexroth Relief Valve DBDH6K18/50 is widely used in industrial hydraulic systems where precise pressure control is required. For example, in the hydraulic system of an injection molding machine, this relief valve can serve as the main pressure control valve, ensuring stable pressure during the injection and holding stages, thereby ensuring consistent product quality.
Construction Machinery: The hydraulic systems of construction machinery such as excavators, loaders, and cranes often experience large load fluctuations. The Rexroth Relief Valve DBDH6K18/50 can be installed at the outlet of a hydraulic pump as a safety valve to prevent damage to hydraulic components caused by excessive system pressure.
Marine and Offshore Engineering: Ship hydraulic systems, such as steering gear systems, crane systems, and anchor winch systems, must operate reliably in harsh marine environments. The corrosion resistance and high reliability of the Rexroth Relief Valve DBDH6K18/50 make it an ideal choice for ship hydraulic systems.
Aerospace: The aerospace industry places extremely high demands on the performance and reliability of hydraulic components. The Rexroth Relief Valve DBDH6K18/50 can be used as a safety valve or pressure regulating valve in hydraulic systems such as aircraft landing gear retraction and extension systems and flight control surface actuation systems.
 

Advantages:

Precise Pressure Control: The Rexroth Relief Valve DBDH6K18/50 utilizes an advanced pilot-operated design, enabling precise pressure control. Its wide pressure setting range allows for flexible adjustment to suit different application scenarios. In hydraulic systems, this relief valve can serve as a constant pressure source, providing a stable oil supply pressure and ensuring the proper operation of hydraulic actuators.
High Reliability: The relief valve body is constructed of high-strength materials, offering excellent pressure resistance and fatigue resistance. The internal sealing elements are made of high-quality sealing materials, ensuring a strong seal even under high pressure and frequent actuation, reducing the risk of leakage. Furthermore, the DBDH6K18/50 relief valve features a sophisticated filter to effectively prevent impurities from entering the valve core area, extending the valve's service life.

Fast Response: The Rexroth Relief Valve DBDH6K18/50 responds quickly to sudden increases in system pressure, opening quickly to drain excess hydraulic fluid back to the tank and maintain stable system pressure. This rapid response is crucial for preventing hydraulic system overloads and protecting hydraulic components from damage.
Easy Installation and Maintenance: The standardized design of this relief valve allows for flexible installation and is easily integrated into existing hydraulic systems. Maintenance is simple, requiring only regular inspection and replacement of sealing elements to ensure long-term, stable operation. This design not only reduces maintenance costs but also improves system availability and reliability.
Energy Saving and Environmental Protection: By precisely controlling hydraulic system pressure, the Rexroth Relief Valve DBDH6K18/50 prevents energy waste caused by excessive pressure. Under low-load conditions, the relief valve automatically reduces system pressure, reducing hydraulic pump energy consumption and achieving energy-saving operation.
