Product Overview
The Rexroth FD 32 FA21/B06V (Material No. R900512105) is a pressure-compensated, two-way flow control valve from the proven Rexroth FD series, designed for precise, load-independent regulation of actuator speed in industrial hydraulic systems. As a pressure-compensated flow control valve, it maintains a constant set flow rate regardless of fluctuating system pressure or load conditions, ensuring stable and repeatable motion control. The valve features a rotary adjustment knob for stepless flow setting and is engineered for inline mounting within the pressure or return line of a hydraulic circuit. With a nominal size of 32 mm and a robust modular design, the FD 32 FA21/B06V is a direct-fit replacement for OEM Rexroth components and is widely deployed in demanding industrial applications where accurate flow metering and consistent actuator velocity are critical.

Engineering Features & Advantages
- Precision Performance: The integrated pressure compensator maintains a constant pressure drop across the metering orifice, delivering load-independent flow regardless of downstream pressure variations — ensuring consistent actuator speed and superior process repeatability.
- Stepless Flow Adjustment: The FA21 rotary knob enables fine, continuous flow setting, allowing operators to tune actuator velocity precisely to match specific process requirements without system modification.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust housing and precision-machined spool designed to withstand high cycle rates and pressure spikes.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in installation without adapter plates or circuit redesign.
- Modular Integration: Designed for seamless integration into Rexroth modular valve systems and standard industrial hydraulic manifolds.
Typical Industrial Applications
The Rexroth FD 32 FA21/B06V pressure-compensated flow control valve is typically deployed in plastic injection molding machines for precise injection and clamping speed control, metallurgical presses requiring accurate ram velocity regulation, CNC machine tools and machining centers for feed axis control, and general heavy industrial hydraulics including construction equipment, marine deck machinery, and test stands where load-independent flow metering is essential for process accuracy and repeatability.</p
