The Bosch Rexroth KSDER0NA/BN0V (R901252718) is a high-performance directional poppet valve designed for efficient hydraulic control within various applications. This direct-operated, screw-in cartridge valve boasts a robust design capable of handling a maximum operating pressure of up to 350 bar (5076 psi) and facilitating a maximum flow rate of 80 l/min (21 gpm). Its Mx cavity ensures compatibility with standardized cavities, making it a versatile choice for integration into diverse hydraulic systems. The KSDER0NA/BN0V features solenoid actuation for on-off control and comes in a normally closed configuration. The valve's poppet type spool ensures tight sealing and reliable performance even after extended periods of non-activity. Its FKM sealing material is suitable for use with various hydraulic fluids, including HL, HLP, HETG, HEPG, and HEES types, ensuring compatibility with standard industry requirements. Engineered for ease of use and maintenance, the KSDER0NA/BN0V includes an integrated coil that can be rotated for convenient installation and service. The solenoids are wet-pin DC types that provide smooth operation. Additionally, the valve offers the option of manual override in concealed or screwable versions for manual actuation when needed. This product falls under the KSDE product family type and is classified within the product group ID as a directional poppet valve that is direct operated with solenoid actuation. It has two ports for hydraulic connections and is designed to be leak-free when blocked on both sides. The compact weight of 0.3 kg makes it suitable for various applications where space and weight are considerations. In summary, the Bosch Rexroth KSDER0NA/BN0V (R901252718) offers reliable directional control in hydraulic systems requiring high-pressure capabilities and leak-free operation. Its robust construction and flexible design ensure it meets the demanding requirements of precise fluid power control applications.

POPPET DIRECTIONAL VALVE KSDER0NA/BN0V

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

Unpacked Weight: 0.2832 kg

Two different mounting cavities, R/B or R/C 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 (see Technical data).

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 for 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).

The screwable manual override (7) is to be screwed back into the initial position after actuation.
