The Bosch Rexroth KKDER1DA/HN0V (R901070118) is a high-performance directional spool valve, designed for direct operation with solenoid actuation. It is a screw-in cartridge valve that fits into a Sun TA cavity and is capable of handling a maximum operating pressure of up to 350 bar (5076 psi) and a maximum flow rate of 80 l/min (21 gpm). This valve features solenoid-actuated on/off control, making it suitable for starting, stopping, and directing the flow of hydraulic fluid in various applications. The KKDER1DA/HN0V valve boasts a direct-acting spool with FKM sealing material for enhanced durability and reliability under different operating conditions. The product type KKDE indicates its classification within Bosch Rexroth's product family as a directional spool valve with direct solenoid actuation. It comes equipped with four ports and utilizes wet-pin DC solenoids for efficient control. The coil is integrated into the design but must be ordered separately. This particular model offers versatility through its bi-directional flow capabilities, allowing hydraulic fluid to be directed in both directions as indicated by symbols D, E, and F. For manual operation, it includes a concealed manual override feature. The valve's weight is optimized for its function without compromising performance. The Bosch Rexroth KKDER1DA/HN0V is compatible with various hydraulic fluids including HL, HLP, HETG, HEES, and HEPG types. Its robust construction ensures reliable operation even in demanding environments. The component series A designation signifies the latest iteration of this model with improved features over previous versions. In summary, the Bosch Rexroth KKDER1DA/HN0V directional spool valve stands out due to its direct-operated design, high-pressure capacity, versatile fluid compatibility, and reliable performance in controlling hydraulic flow within industrial systems.

DIRECTIONAL SPOOL VALVE KKDER1DA/HN0V

4/2 directional spool valve, direct operated with solenoid actuation

Unpacked Weight: 0.35 kg

Mounting cavity R/T-31A Direct-controlled directional slide valve with solenoid actuation Flow possible in both directions Wet-pin DC solenoids Solenoid coil can be rotated With concealed manual override

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 (D; E and F). The main ports ➀, ➁, ➂ and➃can 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).

General information

The 4/2 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).

Attention!

The specified performance limits are valid for use with two directions of flow (e. g. symbol D: ➀ to ➁ and simultaneous return flow from ➃ to ➂). 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 ➀ to ➁ while port B is blocked)! In such cases, please consult us!

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