The Bosch Rexroth KSDER1NB/HN0V (R901083194) is a high-performance directional poppet valve designed for tight, leak-free control within hydraulic systems. As a direct-operated, solenoid-actuated screw-in cartridge valve, it is capable of handling maximum operating pressures up to 350 bar and facilitating a maximum flow rate of 80 l/min. The valve fits into a Sun TA cavity and is engineered for use in applications requiring reliable switching performance, even after extended periods of non-operation. This model boasts a normally closed configuration with the option for manual override, which allows for operation without solenoid power—a feature that can be crucial during maintenance or emergency scenarios. The KSDER1NB/HN0V utilizes FKM sealing material known for its chemical resistance and durability, ensuring longevity and consistent performance. It supports various hydraulic fluids including HL, HLP, HETG, HEPG, and HEES types. Designed with a poppet-type spool and an integrated coil which must be ordered separately, the valve's solenoid coil can be rotated for ease of installation and alignment with system requirements. The product's weight is specified at 0.3 kg, making it relatively lightweight for its capability range. Overall, the Bosch Rexroth KSDER1NB/HN0V offers precise control in hydraulic systems where dependable actuation of fluid direction is critical. Its direct-acting nature ensures that the valve remains pressure-compensated regardless of load variations in the system. With its robust construction and compatibility with various hydraulic fluids, this directional poppet valve stands as an essential component for sophisticated fluid power applications requiring solenoid actuation and reliable performance under high-pressure conditions.

POPPET DIRECTIONAL VALVE KSDER1NB/HN0V

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

Unpacked Weight: 0.281801 kg

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).
