The Bosch Rexroth Z2FS6B3-4X/2QV (R900582339) is a high-performance industrial hydraulic twin throttle check valve designed for reliable flow regulation in hydraulic systems. This mechanically actuated valve features a direct-acting, lockable rotary knob with a scale for precise adjustment, and it is suitable for both main or pilot flow limitation of one or two actuator ports. With its symmetrical design, the Z2FS6B3-4X/2QV allows for controlled flow in one direction while permitting free return flow in the opposite direction. The valve operates by directing hydraulic fluid through a throttling point between the valve seat and throttle spool, which can be adjusted via a setscrew to fine-tune the flow rate. The return flow pushes the valve seat against a spring, enabling unobstructed flow as a check valve. This functionality makes it versatile for either supply or discharge throttling applications. For main flow limitation (Version Q), this model is installed between the directional valve and subplate to adjust actuator velocity. In pilot flow limitation scenarios (Version Q), it is used between the pilot control valve and main valve to manage switching times. The Z2FS6B3-4X/2QV adheres to porting patterns according to DIN form A and ISO with locating hole standards, ensuring compatibility with various system designs. The unit comes in size 6, belongs to component series X, and can withstand a maximum operating pressure of up to 315 bar with a maximum flow rate of 80 l/min. It offers multiple adjustment types including setscrew with lock nut and protective cap, spindle with internal hexagon and scale, alongside the aforementioned rotary knob. The sandwich plate design facilitates easy installation while maintaining a compact footprint within hydraulic circuits. This Bosch Rexroth valve is equipped with FKM seals and supports various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR making it highly adaptable across different system requirements.
