Description:

The Rexroth Relief Valve DBDS20K18/400 is a high-performance, direct-acting pressure relief valve manufactured by Bosch Rexroth of Germany. It is widely used in industrial hydraulic systems to limit system pressure and ensure safe operation. This direct-acting relief valve offers high-precision pressure control and fast response. Its maximum operating pressure is 400 bar, meeting the demands of high-pressure hydraulic systems. Its nominal flow rate is 20 L/min, making it suitable for medium-flow hydraulic systems. This direct-acting valve controls pressure via a spring and a valve core (or ball). When system pressure exceeds the set value, the valve core opens, allowing pressurized fluid to flow from port P to port T. It is equipped with a hexagonal head screw and protective cap for precise pressure adjustment. It utilizes NBR and FKM seals and is suitable for a variety of hydraulic media, including mineral oil and biodegradable oil.

Applications:

Industrial Hydraulic Systems: The DBDS20K18/400 relief valve is widely used in various industrial hydraulic systems, such as injection molding machines, hydraulic presses, and hydraulic presses. In these devices, this valve is used to limit system pressure, prevent equipment damage caused by overpressure, and ensure safe system operation.

Construction Machinery: In construction machinery such as excavators, loaders, and cranes, this valve controls the operating pressure of the hydraulic system, ensuring stability and safety under complex operating conditions.

Metallurgy and Heavy Machinery: In heavy equipment such as steel mills, rolling mills, and presses, this valve protects the hydraulic system from overpressure damage, extending equipment life.

Marine and Shipbuilding: In hydraulic systems of ships, such as steering gear, cranes, and anchor winches, this valve controls hydraulic system pressure, ensuring stable operation in harsh marine environments.

Advantages:

High-Precision Pressure Control: This valve utilizes a direct-acting design, achieving highly accurate pressure control through the precise coordination of the spring and valve core. The set pressure is maintained stable even with varying flow rates.

Fast Response: The direct-acting structure enables the valve to respond quickly, quickly releasing excess pressure in the system and preventing hydraulic shock.

High Reliability: Utilizing high-quality materials and advanced manufacturing processes, this valve exhibits excellent wear resistance and contamination resistance. Its rational structural design allows for easy maintenance and a long service life.
Adaptable to various hydraulic media: This valve is suitable for a variety of hydraulic media, including mineral oil and biodegradable oil. Its seal materials (NBR and FKM) are compatible with different hydraulic fluids, ensuring reliable system operation.
Wide Temperature Range: This valve operates over a wide temperature range. NBR seals are suitable for temperatures from -30°C to +80°C, while FKM seals are suitable for temperatures from -20°C to +80°C, making it suitable for a wide range of environmental conditions.
