The Bosch Rexroth KSDEU1NB/HN0V (R901083202) is a high-quality directional poppet valve, designed for solenoid actuation and characterized by its screw-in cartridge form. This direct operated valve is built to facilitate maximum operating pressures up to bar (psi) while allowing a maximum flow rate of l/min (gpm). The KSDEU1NB/HN0V fits the Sun TA cavity and utilizes an FKM sealing material, ensuring compatibility with various hydraulic fluids such as HL, HLP, HETG, HEPG, and HEES. The valve's design includes a normally closed poppet type spool that ensures leak-free blocking when in the default position. It features a robust build to handle consistent performance demands and is pressure-compensated to mitigate the effects of fluctuating forces on actuation. The product's reliability extends to its ability to switch effectively even after extended periods of non-use. A key feature of this model is its integrated coil, which must be ordered separately; it supports the use of wet-pin DC solenoids and allows for the solenoid coil to be rotated for flexible installation. The KSDEU1NB/HN0V boasts a compact size while belonging to component series B, ensuring it meets standardized dimensions and specifications for ease of integration into various systems. This directional poppet valve is particularly suitable for applications requiring reliable on-off solenoid actuation in hydraulic circuits. Its direct-acting nature ensures quick response times and its design allows for leak-free operation when in the closed position. Additionally, manual override options are available for operation without solenoid energization.

Mounting cavity R/T-13A 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 2/2 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 "P" or normally closed "N") is determined by the position of the closing element (3) and the arrangement of the compression spring (2). Due to the structural design, the 2/2 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).

Attention!

The flow is only admissible in the direction of arrow (see symbols)! With version “U” (operating pressure 500 bar) 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 lower pressure differential.

At symbol "P", the closing element (3) is pressed onto the seat by the solenoid (5), with symbol "N" by the compression spring (2). The flow is blocked in a leak-free manner.

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).
