Rexroth Solenoid Valve R900701407 | Excavator Hydraulic Directional Control Valve

Description

The R900701407 solenoid valve is a Bosch Rexroth-manufactured hydraulic directional control solenoid valve used extensively in the hydraulic systems of hydraulic excavators, material handling equipment, and industrial machinery. The R900701407 is part of Rexroth’s 4WE6 series directional valve family, which is known industry-wide for its superior performance, reliability, and interchangeability across a broad range of hydraulic applications. This valve operates at 24Vdc and provides reliable electromagnetic switching of hydraulic flow in the excavator’s main control valve assembly. The 4WE6 design features a wet-pin armature construction that ensures the spool is pressure-balanced, minimizing the force required from the solenoid coil and extending valve life under high-cycle operating conditions. The R900701407 includes a manual override function allowing emergency actuation of the valve when electrical power is unavailable. With a maximum flow capacity of up to 60 L/min and a pressure rating of 315 bar, this valve handles the substantial hydraulic demands of large-class excavators performing heavy-duty mining, quarrying, and large-scale earthmoving. The valve’s standard ISO 4401 port pattern ensures easy mounting and compatibility with common hydraulic manifold systems. It serves as a direct replacement for worn or failed directional control valves in the hydraulic circuits controlling travel, swing, boom, and bucket functions.
