Product Overview
The Rexroth DA 6 VA2A5X/100FSM (Material No. R901224217) is a direct-operated pressure unloading valve belonging to the proven DA series of pressure control valves. Engineered by Bosch Rexroth, this valve is designed to automatically unload a hydraulic system to tank when a preset pressure threshold is reached, thereby reducing power consumption, limiting heat generation, and protecting downstream components from sustained overpressure. The “100” designation indicates a nominal pressure setting of 100 bar, while the “FSM” suffix denotes the specific adjustment and sealing configuration. With a compact 6-size (NG6 / CETOP 3) subplate mounting interface, the DA 6 VA2A5X is a direct fit for standard industrial manifolds and is widely deployed in accumulator charging circuits, high-low pump systems, and pressure-holding applications requiring reliable, repeatable unloading behavior.
