Product Overview
The Rexroth Z2FS 6-2-4X/2QV (Material No. R900481624) is a twin throttle check valve from the proven Z2FS series, designed for precise flow control in industrial hydraulic systems. Configured as a sandwich (modular) plate valve in size NG6 (CETOP 3 / ISO 4401-03), it integrates two independently adjustable throttle paths with integral check valves, enabling accurate meter-in or meter-out speed regulation of actuators in both flow directions. The valve is part of the 4X component series and is engineered for direct mounting between a directional control valve and the subplate, providing a compact, leak-tight modular solution for demanding motion control circuits.
