The Bosch Rexroth DBW10BG2-4X/200-6EG24N9K4W65 (R900929383) is a high-performance industrial hydraulic valve designed for reliable pressure relief and solenoid-actuated unloading. This pilot-operated valve is adept at maintaining precise control over operating pressures within hydraulic systems. It features a spool symbol P T and can handle a maximum pressure that ensures robust performance in demanding applications. With its solenoid actuation, the DBW10BG2-4X/200-6EG24N9K4W65 valve offers efficient control, allowing for smooth transitions and accurate pressure management. The unit is equipped with a threaded connection type, facilitating secure integration into various hydraulic circuits. It operates on a 24 VDC supply voltage and has multiple switching positions to cater to different operational requirements. The valve boasts an impressive maximum flow rate, which ensures that it can cope with high-demand scenarios without compromising on performance or safety. The weight of the unit is optimized for its size and functionality, ensuring that it does not add unnecessary bulk to the system it serves. In terms of usability, this model comes with various adjustment types for pressure settings, including options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale. These features provide users with flexibility and precision when adjusting the valve to meet specific system requirements. Additionally, the DBW10BG2-4X/200-6EG24N9K4W65 valve incorporates NBR seals compatible with hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC. This compatibility range ensures that the valve can be used across different systems without concern for fluid-induced degradation. The design includes a built-on directional spool valve for solenoid-operated unloading and an internal pilot control valve mechanism that guarantees stability even under fluctuating pressure conditions. With its robust construction and advanced features, this Bosch Rexroth hydraulic valve stands out as an essential component for efficient pressure management in industrial hydraulic systems.
Size 10, P → T, solenoid-actuated, 24 V DC
Industrial hydraulic valve in a high performance range. Reliable pressure relief to setting value.
Unpacked Weight: 5.300 kg
Valves of type DBW are pilot-operated pressure relief valves. They are used for limitation and solenoid-actuated unloading of the operating pressure.
The valves basically consist of housing (1) and pilot control valve (2) with adjustment type.
The pressure applied to channel P acts on the main spool (3). Via the nozzle bores (4 and 5), the pressure is at the same time applied to poppet (6). If the pressure in channel P exceeds the value set at spring (7), poppet (6) opens against spring (7). Via the nozzle bores (4 and 5), the hydraulic fluid from channel P now flows into the spring chamber (8). From here, it is led into the tank internally (version "–"), via the control line (9 and 10), or externally (version "Y") via the control line (9 and 11).
Due to the state of equilibrium at the main spool (3), hydraulic fluid flows from channel P to channel T, maintaining the set operating pressure.
A pressure gauge connection (12) allows for the control of the operating pressure.
The pressure relief valve can be unloaded or switched to another pressure (second pressure rating) via port X (13).
The main spool (3) is unloaded by controlling a built-on directional valve.

Important information on hydraulic fluids: For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature.Bio-degradable: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system. |

The unloading function (directional valve function with version "W") must not be used for safety functions! With version "B", the lowest adjustable pressure (circulation pressure) is set in case of power failure or cable break. With version "A", the pressure limiting function is set in case of power failure or cable break. Hydraulic counter pressures in port T with internal pilot oil return and/or port Y with external pilot oil return add 1:1 to the response pressure of the valve set at the pilot control.
Example:
Pressure adjustment of the valve due to spring pretensioning (item 7 on Product description) in the pilot control valve/adjustment type
pspring = 200 bar
Hydraulic counter pressure in port T with internal pilot oil returnphydraulic = 50 bar
⇒ Response pressure= pspring + phydraulic = 250 bar
