The Bosch Rexroth DB10-1-5X/200XCV (R901394307) is a sophisticated pilot-operated pressure limitation valve designed to effectively limit operating pressure within hydraulic systems. Comprising a main valve with a spool insert, a pilot control valve, and a closing plate, this device ensures precise pressure regulation. The pressure in channel P influences the main spool while also being directed through control lines to both the spring-loaded side of the main spool and the ball in the pilot control valve. When the pressure exceeds a preset value, it causes the ball to open against its spring, allowing hydraulic fluid to flow and maintain the set operating pressure. This model features subplate mounting with porting patterns that adhere to ISO standards NG6, NG10, and NG16 for versatile integration into various hydraulic setups. The adjustment type is via a rotary knob which allows for easy setting of pressure ratings. It is engineered for maximum operating pressures up to 350 bar and can be utilized in environments requiring adherence to Explosion Protection Directive EU standards: IM, IIG, IID. The types of protection for this valve are certified as 'c' according to EN standards. Additionally, an extra directional spool valve type WE can be attached for solenoid-actuated unloading capabilities. This feature enhances the functionality of the DB10-1-5X/200XCV valve by allowing it to be relieved or switched to alternate pressures when necessary. The Bosch Rexroth DB10 series valves are well-suited for applications demanding reliable and accurate pressure limitation in hydraulic systems where safety and performance are paramount. This particular model's robust design ensures it meets stringent operational requirements while providing flexibility in application due to its compatibility with various protection types and explosion-proof standards.

Valves of type DB are pilot-operated pressure limitation valves. They serve to limit the operating pressure and mainly consist of the main valve (1) with main spool insert (3), the pilot control valve (2) and the closing plate (16).

The pressure in channel P acts on the main spool (3).

Simultaneously, the pressure is applied via the control lines (6) and (7), which are equipped with nozzles (4) and (5), to the spring-loaded side of the main spool (3) and to the ball (8) in the pilot control valve (2). If the pressure in channel P is increased due to the value which is set at the spring (9), the ball (8) opens against the spring (9). The signal for this is sent internally via the control lines (10) and (6) from channel P. The hydraulic fluid on the spring-loaded side of the main spool (3) now flows via the control line (7), nozzle bore (11) and ball (8) in the spring chamber (12). From here, it is passed on to the container internally with type DB...–... via control line (13) or externally with type DB...Y... via control line (14). Due to nozzles (4) and (5), there is a pressure drop at the main spool (3). The connection from channel P to channel T is free. Now, the hydraulic fluid flows from channel P to channel T while the set operating pressure is maintained.

Via port "X" (15), the pressure relief valve can be relieved or switched to a different pressure (second pressure rating).

Notice:

With the attachment of an additional directional spool valve type 3WE 6…, the valve can be extended for solenoid-actuated unloading (see chapter "Project planning information", "Solenoid-actuated unloading").

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: Small amounts of dissolved zinc may get into the hydraulic system during use of these hydraulic fluids.

General Information

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 (see chapter "Product description" item 12) in the pilot control valve/adjustment unit: pspring = 200 bar

Hydraulic counter pressure in port T with internal pilot oil return: phydraulic = 50 bar

⇒ Response pressure = pspring + phydraulic = 250 bar

Solenoid-actuated unloading

By mounting a directional spool valve type 3WE 6…, the valve can be modified so that it can be switched to depressurized circulation (main control spool unloaded) by means of electrical control.

Before mounting a directional spool valve 3WE 6… at a pilot-operated pressure relief valve DB…XC, it has to be checked whether the category and protection class resulting from the combination satisfy the requirements of the relevant potentially explosive area.

The directional spool valves suitable for mounting and the resulting categories and protection classes can be seen from the following table.

Important notices:

The unloading function with directional valve must not be used for safety functions. In the assembly, the corresponding operating instructions included in the scope of delivery of the directional spool valves are to be observed. Any mounting and/or modification without operating instructions is not admissible. Before the assembly, all parts are to be identified using the relevant name plates.

The directional spool valve determines the category according to the explosion protection directive 2014/34/EU:

Directional spool valve	Category according to 2014/34/EU	Data sheet
3WE 6…5X/…XH	II2G	23177-XH
3WE 6…5X/…XM	IM2	23177-XH
3WE 6…6X/…XD	IM2; II2G	23178-XD
3WE 6…6X/…XE	II2G	23178-XE
3WE 6…6X/…XN	II3G; II3D	23178-XN
Example: DB…XC plus 3WE 6…6X/…XN1) results in the possible use in category II3G; II3D

1)	Please also observe the possible circuit variations when selecting a valve.
