The Bosch Rexroth KKDER1CA/HN9V (R901070103) is a high-performance directional spool valve, designed for direct operation with solenoid actuation. This screw-in cartridge valve is part of the product family classification of direct operated directional spool valves and falls under the product group ID of KKDE. The valve boasts a maximum operating pressure of up to 350 bar and can handle a maximum flow rate that ensures efficient performance in various hydraulic applications. Featuring a Sun TA cavity, the KKDER1CA/HN9V valve is compatible with multiple hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HEES, HEPR, HEPG, HFDU, HFDR, and HFAS. It is equipped with wet-pin DC solenoids that ensure reliable actuation of the control spool. The manual override feature is concealed but allows for manual operation of the valve if necessary. The valve's construction includes a housing with a movable socket and a control spool which are both essential for its function. A return spring maintains the control spool in its initial position when de-energized. The main ports can sustain continuous operating pressure allowing for flow in both directions as per user requirements. This model has been engineered to provide precise control over the start, stop, and direction of flow in hydraulic systems. It features an integrated coil that must be ordered separately and has a nominal flow rate for efficient operation. The poppet-type spool within this component series A size valve ensures smooth operation and longevity. Overall, the Bosch Rexroth KKDER1CA/HN9V offers robust performance for industrial applications requiring precise hydraulic control with its direct-acting design and versatile compatibility with various fluid types.

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).
