Product Overview
The Rexroth Z2FS6-2-4X/20V (Material No. R900481624) is a high-precision twin throttle check valve designed for sandwich plate mounting within industrial hydraulic systems. As a member of the Rexroth Z2FS series, this component functions as a flow control and modular valve, providing independent and precise metering of flow in both directions of a hydraulic circuit. The “twin” configuration allows for the simultaneous regulation of two separate flow paths, typically used to control the speed of a double-acting actuator or to balance flow in dual-line systems. This valve is engineered to maintain stable performance under varying pressure and temperature conditions, ensuring accurate velocity control and reliable load holding in demanding industrial environments.

Engineering Features & Advantages
- Precision Performance: Twin throttle design enables independent, stepless adjustment of flow in two separate lines, providing accurate speed control for double-acting cylinders and motors.
- Integrated Check Function: Each throttle path includes a check valve that permits free flow in the opposite direction, ensuring unrestricted return flow and preventing unintended reverse movement.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust housing and hardened internal components for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including the ISO 4401-03 mounting pattern for seamless integration into existing manifolds.
- Stable Metering: Pressure-compensated design maintains consistent flow rates despite fluctuations in system pressure and temperature, enhancing process repeatability.
Typical Industrial Applications
This twin throttle check valve is commonly employed in plastic injection molding machines for precise mold movement control, metallurgical presses for synchronized ram speed, CNC machine tools for accurate feed axis regulation, and construction & marine hydraulics for reliable actuator positioning. Its modular design allows for easy stacking with other ISO 4401-03 valves, making it a versatile solution for complex hydraulic circuits requiring independent flow control in multiple lines.
