Product Overview
The Rexroth MG 8 G14/V (Material Number R900438885) is a precision-manufactured throttle valve from the proven Rexroth MG series of modular hydraulic valves. Operating on the principle of variable annular gap restriction, this valve regulates volumetric flow rate by adjusting the throttling cross-section through a manually actuated rotary knob, thereby controlling actuator speed independently of system pressure. The MG 8 G14/V is designed as a sandwich (modular) plate valve for direct mounting between a directional control valve and its subplate, conforming to ISO 4401 / DIN 24340 interface standards. With a nominal size of NG 8 (D08) and a G14 throttle insert, it delivers fine, repeatable flow metering in demanding industrial hydraulic circuits where precise velocity control of cylinders and motors is essential.

Engineering Features & Advantages
- Precision Flow Metering: The G14 throttle insert provides a finely graduated annular restriction, enabling accurate, repeatable adjustment of volumetric flow for precise actuator speed control.
- Pressure-Independent Throttling: The throttle principle regulates flow via the throttling cross-section, allowing consistent speed setting behavior across varying load conditions within the circuit.
- Modular Sandwich Construction: Compact NG 8 plate design mounts directly between the directional valve and subplate, minimizing piping, reducing leakage points, and simplifying system integration.
- Industrial Reliability: Designed for dependable long-term operation in demanding industrial environments, with quality bearings and sealing systems ensuring extended maintenance intervals.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
