Product Overview
The Rexroth 04330500 / 850000A is a solenoid-actuated directional cartridge valve engineered for precise control of hydraulic fluid flow direction within high-pressure industrial circuits. Manufactured by Bosch Rexroth, this 2-position / 4-way (2/4) directional spool valve utilizes a wet-pin AC or DC solenoid to shift an internal spool, thereby connecting or isolating specific ports (P, T, A, B) to direct actuator movement. Designed as a slip-in cartridge, it is typically mounted into a pre-machined manifold block, offering a compact, leak-resistant solution for controlling cylinders, motors, and rotary actuators in demanding hydraulic power units and mobile machinery. The 850000A designation indicates a specific spool type and voltage configuration within the Rexroth standard program, ensuring direct interchangeability with original system components.

Engineering Features & Advantages
- Precision Spool Metering: The hardened, ground spool and sleeve assembly ensures minimal internal leakage and precise flow control, enabling accurate actuator positioning and smooth directional transitions.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust solenoid coil rated for high cycle rates and a cartridge body designed to withstand pressure spikes and contamination.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including the 04330500 / 850000A part numbers, ensuring drop-in replacement without manifold modification.
- Compact Cartridge Design: Slip-in cartridge reduces installation space and eliminates external leakage paths associated with subplate-mounted valves, simplifying manifold integration.
- Fast Response: Low-inertia spool and high-force solenoid provide rapid shifting times, typically 20–50 ms, ideal for high-cycle industrial automation.
