The Bosch Rexroth OD141078KK2000-VEDS-10A-4310 (R901237595) is a high-performance screw-in cartridge valve designed for hydraulic applications requiring precise control over the start, stop, and direction of fluid flow. This direct-acting spool valve is pressure-compensated and integrates seamlessly into various hydraulic systems with its CAAN cavity design. With a maximum operating pressure of 350 bar (5075 psi) and a nominal flow rate capacity, it is built to handle significant flow rates while maintaining stability and performance. The OD141078KK2000-VEDS-10A-4310 features solenoid actuation for on/off control, ensuring reliable operation with its wet-pin DC solenoids. It offers flexibility in system design thanks to its four-way, three-position spool configuration. The valve's spool type is a poppet, which contributes to its ability to provide secure sealing and efficient flow control within the hydraulic circuit. Constructed with FKM sealing material, this valve is compatible with hydraulic fluids such as HL and HLP, ensuring longevity and resistance to harsh operating conditions. Its coil is integrated yet can be ordered separately if needed, and the solenoid coil can be rotated for ease of installation. Moreover, the manual override feature allows operators to manually switch the valve in instances where solenoid energization isn't possible or desirable. Weighing in at 0.55 kg, the Bosch Rexroth OD141078KK2000-VEDS-10A-4310 offers a robust solution for engineers looking to implement a reliable valve that provides both direct and pilot operation in their hydraulic systems. Whether utilized in industrial machinery or mobile applications, this product delivers precision control when it comes to managing fluid dynamics within complex hydraulic circuits.

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.
