Bosch Rexroth R902603434 Proportional Solenoid

The Bosch Rexroth R902603434 is a 24V DC proportional solenoid designed for electro-hydraulic control of directional and pressure valves. It features the manufacturer model code GRCY037N54L15-002-24V and serves as the actuation element for Rexroth proportional valve series including EZ and EP control modules. Technical construction utilizes a wet-pin armature design with corrosion-resistant materials suitable for mineral oil based hydraulic fluids. The solenoid generates proportional force output relative to input current, enabling precise spool positioning for flow and pressure regulation in mobile and industrial hydraulic circuits. Cross-reference interchange includes Wirtgen OEM 2081442, Rexroth service number 182662, and alternative formatting GRCY037N54L1500224V. Typical applications span axial piston pump controls (A11VO, A4VG series) and pilot valve actuation on construction machinery hydraulic systems.
