The Bosch Rexroth KSDER1CB/HN11V (R901151279) is a high-performance directional poppet valve characterized by its direct operation with solenoid actuation. This screw-in cartridge valve is designed to manage flow with precision, featuring a maximum operating pressure of up to 350 bar (5076 psi) and a maximum flow rate of 80 l/min (21.1 gpm). It is engineered for use within the Sun TA cavity and employs an FKM sealing material for optimal performance in various hydraulic systems. The KSDER1CB/HN11V valve offers both normally open and normally closed configurations, ensuring versatility for different circuit designs. Its pressure-compensated structure allows consistent operation regardless of fluctuating pressures, while the solenoid-actuated on/off functionality provides reliable control for hydraulic circuits. The manual override feature, available in concealed or screwable versions, adds an extra layer of control by allowing manual operation in the absence of solenoid power. This model boasts a poppet-type spool ensuring tight sealing and minimal leakage across ports in its default position. Additionally, it has been designed to ensure reliable switching even after extended periods without activity, thanks to its wet-pin DC solenoids and the ability to rotate the solenoid coil for ease of installation. The Bosch Rexroth KSDER1CB/HN11V valve is compatible with a range of hydraulic fluids including HL, HLP, HETG, HEPG, and HEES types. Its robust construction and advanced design make it suitable for demanding applications where precise flow control and durability are critical. The product's direct acting feature offers simplicity and reliability in function, making it an essential component for efficient hydraulic system operations.
3/2 directional poppet valve, direct operated with solenoid actuation
Unpacked Weight: 0.3189 kg
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).
