The Bosch Rexroth KKDER1UA/HN0V (R901070099) is a high-performance directional spool valve, expertly designed for direct operation with solenoid actuation. This screw-in cartridge valve is part of the distinguished KKDE product family, renowned for its reliability and precision in controlling the start, stop, and direction of fluid flow in hydraulic systems. The valve boasts an impressive maximum operating pressure of 350 bar and can facilitate a maximum flow rate of 80 liters per minute, making it suitable for a variety of demanding applications. Equipped with an integrated wet-pin DC solenoid, the KKDER1UA/HN0V ensures efficient actuation with the added benefit that the solenoid coil can be rotated for ease of installation and maintenance. Additionally, this model features a manual override that is discretely designed and can be operated without solenoid energization—enhancing its functionality during system troubleshooting or emergency situations. The valve's construction includes a durable housing with a movable socket, a control spool, and a return spring to maintain the spool's position when de-energized. It has been engineered to accommodate continuous loading on its main ports A and B at full operating pressure while allowing flow in both directions—a testament to its versatile design. This particular model utilizes FKM sealing material for superior chemical resistance and operates effectively with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS. The KKDER1UA/HN0V is also characterized by its direct-acting spool type which contributes to its compact size and robust performance. With Sun TA cavity compatibility and designed for easy integration into existing systems as a screw-in cartridge valve; this Bosch Rexroth directional spool valve stands out as an essential component for sophisticated hydraulic solutions.

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).
