The Rexroth Z2FS6A2-46/2QV is a high-performance double throttle check valve designed for precise hydraulic flow control. As a sandwich plate valve of size NG6, it is intended for vertical stacking assemblies, mounting between a directional valve and a subplate or manifold. This model provides meter-in or meter-out control by throttling the flow in port A and allowing free return flow through the check valve in port B. It features a user-friendly rotary knob with an integrated scale for easy and repeatable flow adjustments. Constructed with FKM (Viton) seals, this valve is compatible with a wide range of hydraulic fluids and operating temperatures, ensuring reliability and versatility in demanding industrial applications.
