The Rexroth Z2FS 6 B2-4X/1QV is a high-performance double throttle check valve designed for precise hydraulic flow control. As a sandwich plate valve, it is intended for vertical stacking assemblies and installs directly between a directional valve and the subplate. This model provides meter-in or meter-out control by throttling the flow in ports A and B, while allowing free return flow via integrated check valves. The valve is easily adjusted using a rotary knob with a scale, enabling fine-tuning of actuator speed. Built to Rexroth’s exacting standards, the Z2FS 6 is ideal for applications requiring reliable and adjustable speed control of hydraulic cylinders or motors.
