The Bosch Rexroth KKDER1CA/HN0V (R901070094) is a high-performance directional spool valve, expertly designed for direct operation with solenoid actuation. This screw-in cartridge valve is engineered to control the start, stop, and direction of a hydraulic flow with precision. It boasts a maximum operating pressure of 315 bar and can accommodate a maximum flow of up to 80 l/min, making it suitable for a wide range of demanding applications. The valve incorporates a housing with a movable socket, control spool, and return spring. In its default state, the control spool is maintained in position by the return spring but can be actuated by the wet-pin DC solenoids that come integrated into the design. The different symbols for controlling flow are achieved using various spools designated as C or U types. Main ports A, B, and P are capable of handling continuous operating pressures up to 315 bar while allowing bi-directional flow. Additionally, this model features concealed manual override functionality that permits manual operation of the valve in situations where solenoid power is unavailable. The solenoid coil on this unit can be rotated for flexible installation orientations. Its compact size and component series A designation ensure it fits within standardized cavity Sun TA. The Bosch Rexroth KKDER1CA/HN0V valve is characterized by its poppet spool type and has been classified under product family type KKDE with ports number 3 and sealing material FKM suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS. This product's robust design ensures reliability in controlling hydraulic systems while maintaining efficiency in both industrial settings. Its direct-acting feature provides responsive performance for systems requiring precise control over their hydraulic functions.

General information

The 3/2 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 a housing (1) with moveable 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). The symbols are realized by different spools (C or U). The main ports ➀, ➁ and ➂ can be loaded continuously with an operating pressure of 350 bar and the flow can be directed into both directions (see Symbols).

The manual override (6) allows for the switching of the valve without solenoid energization. It is also available in screwable version"N10" (7) (see Type keys).

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 process and operating medium used must be 40 K over the maximum solenoid surface temperature. Flame-resistant – containing water: The maximum pressure differential per control edge is 175 bar. Otherwise, there is increased cavitation erosion. Tank preloading < 1 bar or > 20% of the pressure differential. The pressure peaks should not exceed the maximum operating pressures! Environmentally compatible: When using environmentally compatible hydraulic fluids that are simultaneously zinc-solving, zinc may accumulate in the medium (700 mgzinc per pole tube).
