Product Overview
The Rexroth DBW30B2-5X/315-6EG24N9K4 (Material Number R900922311) is a pilot-operated, solenoid-controlled pressure relief valve from the renowned Rexroth DBW series. This valve is designed to limit and electrically unload system pressure in hydraulic circuits, providing precise pressure control and safe operation. It combines a pilot-operated pressure relief valve with a directional spool valve, allowing for solenoid-actuated unloading of the main stage. The DBW30B2-5X/315-6EG24N9K4 is widely used in industrial hydraulic systems where reliable pressure limitation and electrical venting are required, such as in presses, injection molding machines, and test rigs. With a nominal size of 30 (NG30) and a pressure rating of 315 bar, it ensures robust performance and long service life even under demanding conditions.
