The Bosch Rexroth DBT-XP7-1X/315 (0811104105) is a direct-operated, seat-designed pressure relief valve that serves as a critical component in hydraulic systems for controlling and limiting system pressure. This model is specifically constructed for remote control applications and is capable of manual adjustments via its adjustment type (4). The valve's construction includes a robust housing (1), a precisely machined valve poppet (2), and a corresponding valve seat (3), ensuring reliable operation and performance. In its default state, the valve poppet (2) is in contact with the valve seat (3), effectively blocking the passage between the P and T connections to maintain system stability. The hydraulic force required to activate the valve corresponds to the force preset at the adjustment type (4). When this force threshold is met, the DBT-XP7-1X/315 responds by lifting the poppet away from its seat, allowing excess hydraulic fluid to flow from P to T, thereby controlling and maintaining the set pressure within safe limits. An important feature of this model is that even with a completely unloaded spring (5), it ensures a minimum pressure of 3 bar due to spring preload force. This guarantees that even at low pressures, there will be some level of controlled resistance. Typically employed as pilot control valves for indirect management of larger flow rates, these valves are versatile for various applications requiring precise pressure modulation. They are designed for subplate mounting or integration into control panel designs, highlighting their adaptability in different system configurations. The Bosch Rexroth DBT-XP7-1X/315 stands out for its reliability and efficiency in maintaining hydraulic system integrity through accurate pressure relief functions.
Pressure relief valves of type DBT are remote control valves with seat design and are used for limiting a system pressure.
The setting is completed manually, via the adjustment type (4).
The valves basically consist of the housing (1), the valve poppet (2) and the related valve seat (3).
In the unloaded position, the valve poppet (2) pushes onto the valve seat (3) and blocks the connection between P and T connection.
If the hydraulic force equals the force set at the adjustment type (4), the valve controls the set pressure.
By lifting off the valve poppet (2) from the valve seat (3), the excessive hydraulic fluid may flow off from P to T.
With completely unloaded spring (5), the minimum pressure of 3 bar (spring preload force) will settle.
These valves are basically used as pilot control valves for the indirect control of larger flows.
