The Bosch Rexroth OD141078KK2100-VEDS-10A-4310-M1 (R901255425) is a high-performance screw-in cartridge valve designed for precise hydraulic fluid control in demanding applications. This direct-acting spool valve is capable of handling a maximum operating pressure of up to 350 bar (5076 psi) and has a maximum flow rate of 120 l/min (31.7 gpm). It is built to fit the standard cavity CAAN, ensuring compatibility with various hydraulic systems. The OD141078KK2100-VEDS-10A-4310-M1 features a solenoid-operated on/off function, with a direct spool type actuation, which ensures reliable performance when starting, stopping, or directing flow. The valve includes an integrated coil that must be ordered separately and can be rotated for ease of installation. The manual override option provides push and pull functionality, allowing operators to manually switch the valve in the absence of solenoid power. This product falls under the VEDS product family type within Bosch Rexroth's extensive range of solenoid-operated valves and is classified as a 4-way position valve. It utilizes FKM as its sealing material, which offers excellent chemical resistance and durability under various operating conditions. The valve has four ports: P (Pump), A (Actuator), B (Actuator), and T (Tank), each designed to withstand continuous pressure during operation. For added versatility, the OD141078KK2100-VEDS-10A-4310-M1 allows for an optional auxiliary operating device and employs wet-pin DC solenoids known for their robustness in wet environments. Weighing approximately 0.8 kg, this compact valve is suitable for integration into a wide range of hydraulic circuits that require HL or HLP hydraulic fluids. In summary, the Bosch Rexroth OD141078KK2100-VEDS-10A-4310-M1 screw-in cartridge valve offers exceptional control capabilities with its robust design and flexible features, making it an essential component for sophisticated hydraulic systems requiring precise flow management.

General information

The 4/3 directional spool valves are direct operated, pressure-compensated screw-in cartridge valves. They control the start, stop and direction of flow and basically consist of pole tube (1), socket (2), a control spool (5) and a return spring (4).

Function

In the de-energized condition, the control spool (5) is held in the initial position by the return spring (4). The control spool (5) is actuated by wet-pin DC solenoids (3.1; 3.2). The symbols are realized by different spools (“10”; “20”; “40” and "60"). The main ports ➁, ➂ and ➃ can be pressurized continuously with an operating pressure of 350 bar. The ports have a fixed pin assignment (see Symbols). At port ➀, there may be a maximum pressure of 250 bar.

The manual override (6) allows for the switching of the valve without solenoid energization.

Important information on hydraulic fluids! For further information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The flash point of the hydraulic fluids used must be 40 K higher than the maximum solenoid surface temperature. Bio-degradable: If bio-degradable hydraulic fluids are used that are also zinc-solving, there may be an accumulation of zinc.

In the electrical connection, the protective earthing conductor (PE, grounded) is to be connected in accordance with the stipulations.

Attention!

The specified performance limits are valid for use with two directions of flow (e. g. from ➂ to ➁ and simultaneous return flow from ➃ to ➀). Due to the flow forces acting within the valves, the admissible performance limit may be considerably lower with only one direction of flow (e. g. from ➂ to ➁ while port ➃ is blocked)!

In such use cases, please consult us!

The performance limit was determined when the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.
