The Bosch Rexroth Z2FS6-5-4X/1QV (R900582719) is a high-performance industrial hydraulic valve designed for precise flow throttling to a set value. This direct-actuated valve features a spindle with an internal hexagon and scale for fine adjustments, allowing for reliable control over hydraulic fluid flow. The spool symbol can be either A A, B B or A A, B B, and it includes mechanically actuated throttling for one or two actuator ports. The Z2FS6-5-4X/1QV is part of the ZFS series, which includes twin throttle check valves in a sandwich plate design. The valves are symmetrical, providing flow limitation in one direction while allowing free return flow in the opposite direction. This is achieved through an axial adjustment of the throttle spool via a setscrew, which adjusts the throttling point for precise fluid control. This model can serve as either a main flow limitation or pilot flow limitation device. When used for main flow limitation, it is installed between the directional valve and the subplate to adjust actuator velocity. For pilot-operated directional valves, it serves to adjust switching times when installed between the pilot control valve and the main valve. The Bosch Rexroth Z2FS6-5-4X/1QV offers various adjustment types including a setscrew with lock nut and protective cap, lockable rotary knob with scale, and rotary knob with scale suitable for both supply or discharge throttling applications. It adheres to porting patterns according to DIN and ISO standards with locating holes suitable for sandwich plate installation. It also features a maximum operating pressure and maximum flow rate that ensure efficient performance across different hydraulic systems while utilizing FKM seals compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR.
