Product Overview
The Rexroth Z2FS 16A8-31/S2 (Material No. R900348227) is a high-performance twin throttle check valve designed for precise flow control in industrial hydraulic systems. Manufactured by Bosch Rexroth, this modular valve is part of the Z2FS series, which is engineered to regulate the flow rate of hydraulic fluid in two directions independently. The valve features a sandwich plate design, allowing for direct mounting between a directional control valve and a subplate, thereby eliminating the need for additional piping. The Z2FS 16A8-31/S2 is specifically configured for meter-in or meter-out flow control, providing reliable and repeatable speed regulation for actuators. Its robust construction and precision-engineered throttling spools ensure minimal pressure loss and stable operation, making it an essential component for demanding industrial applications requiring accurate motion control.

Engineering Features & Advantages
- Precision Flow Control: Twin throttle design allows independent adjustment of flow in both directions, enabling accurate meter-in or meter-out control for symmetrical or asymmetrical actuators.
- Integrated Check Function: Each throttle path includes a check valve that permits free flow in the opposite direction, ensuring unrestricted return flow and preventing reverse flow interference.
- Modular Sandwich Construction: Compact sandwich plate design simplifies installation between directional valve and subplate, reducing space requirements and piping complexity.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened throttling spools and robust housing for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification.
Typical Industrial Applications
This twin throttle check valve is widely used in heavy industrial scenarios requiring precise speed control of hydraulic actuators, such as plastic injection molding machines, metallurgical presses, CNC machine tools, and construction & marine hydraulics. It is particularly suited for systems where independent flow regulation in both directions is essential for synchronized or sequential motion control.
