The Bosch Rexroth KSDEU1CB/HN0V (R901083198) is a high-performance directional poppet valve designed for demanding hydraulic applications. This direct-operated screw-in cartridge valve features solenoid actuation and is built to handle a maximum operating pressure of up to 350 bar (5076 psi), with a maximum flow rate of 80 l/min (21 gpm). It is engineered to fit the Sun TA cavity, ensuring compatibility with standardized configurations. The KSDEU1CB/HN0V valve is characterized by its robust poppet-type spool that provides reliable on-off control in hydraulic circuits. The solenoid-actuated design ensures precise operation, while the FKM sealing material offers excellent resistance to high temperatures and chemical degradation, ensuring long-term durability and performance in various environments. The valve's direct-acting nature guarantees swift response times and reliable switching performance, even after extended periods of non-activity. Additionally, this model boasts several user-friendly features such as an integrated coil that can be rotated for ease of installation, and the option for manual override which allows for manual actuation of the valve in the absence of electrical power. The manual override comes in two styles: concealed or screwable versions, providing flexibility for different operational requirements. Designed with a focus on reliability and efficiency, the Bosch Rexroth KSDEU1CB/HN0V valve ensures leak-free blocking in both end positions, making it an ideal choice for applications requiring tight shut-off. Its flow-optimized construction enables greater switching power, enhancing overall system performance. The product falls within the product family classification of directional poppet valves and carries a weight specification of 0.3 kg. It is compatible with various hydraulic fluids including HL, HLP, HETG, HEPG, and HEES types.

POPPET DIRECTIONAL VALVE KSDEU1CB/HN0V

3/2 directional poppet valve, direct operated with solenoid actuation

Unpacked Weight: 0.3 kg

Mounting cavity R/T-11A Direct operated directional seat valve with solenoid actuation, tight on both sides Blocked port tight in a leak-free form Reliable switching even after longer periods of standstill Wet-pin DC solenoids Solenoid coil can be rotated

General

The 3/2 directional seat valves are direct operated, pressure-compensated screw-in cartridge valves. They basically consist of a screw-in section (4) with valve seat (1), solenoid (5) as well as closing element (3) and compression spring (2).

Function

The initial position of the valve (normally open “U" or normally closed “C") is determined by the position of the closing element (3) and the arrangement of the compression spring (2). Due to the structural design, the 3/2 directional seat valves are always pressure-compensated in relation to the actuating forces. The main ports ➀ and ➁ can be loaded with an operating pressure of 350 bar/500 bar (see Technical data) and are blocked in a leakage-free manner in the respective end position. While switching, the main ports are connected for a short period of time (negative overlap).

Attention!

The flow is only admissible in the direction of arrow (see symbols)! With version “U” (operating pressure 500 bar [7250 psi]) as well as with version “R...-17”, the main port ➀ is to be connected to the pump connection P! The valves of version “R...-17” are flow-optimized and thus achieve a greater switching power.

The manual override allows the switching of the valve without solenoid energization. It is available in concealed version "N9" (6) or in screwable version "N11" (7) (see ordering codes).
