The Bosch Rexroth KSDER1PB/HN9V (R901151294) is a high-performance directional poppet valve, designed for direct operation with solenoid actuation. This screw-in cartridge valve is capable of handling a maximum operating pressure of up to 350 bar (5076 psi) and allows for a maximum flow of 60 l/min (15.9 gpm). It features a Sun TA cavity and comes equipped with an integrated Coil GZ which must be ordered separately.
This model falls under the product family classification of directional poppet valves and is identified as a KSDE type within the product group. The KSDER1PB/HN9V offers a direct-acting, solenoid-actuated on/off control with concealed manual override options. Its spool type is a poppet, ensuring reliable performance in hydraulic systems utilizing fluids such as HL, HLP, HETG, HEPG, and HEES.
The valve's normal position is normally open, with its nominal flow directly controlled through its 3-way ports number configuration. The sealing material used in this model is FKM, which provides excellent resistance to high temperatures and chemical exposure. With its robust construction and pressure-compensated design, the KSDER1PB/HN9V ensures leak-free blocking of flow when in the closed position.
This Bosch Rexroth valve is particularly suitable for applications requiring precise control over fluid direction and flow within hydraulic systems. Its high-pressure capability makes it an ideal choice for demanding applications where reliability and performance are critical. The manual override feature adds an additional layer of operational security by allowing manual operation in the absence of electrical power to the solenoid.

2/2 directional poppet valve, direct operated with solenoid actuation
Unpacked Weight: 0.2807 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).
