The Rexroth ZDB 6VA1-42/100V is a high-performance, direct-operated pressure relief valve designed in a sandwich plate configuration. It is engineered to limit the pressure in a hydraulic system by opening a passage to the tank when the set pressure is reached. This model is part of the ZDB 6 series, featuring a nominal size of NG6, making it suitable for vertical stacking assemblies conforming to ISO 4401 standards. The valve includes a rotary knob (VA1) for convenient and precise adjustment of the pressure setting up to 100 bar. Its robust construction ensures reliable performance and protection for hydraulic circuits and components.
