Product Overview
The Rexroth ZDB6VB2-4X/200V is a direct-operated pressure relief valve from the proven ZDB6 series, designed for precise pressure limiting and system protection in industrial hydraulic circuits. As a pressure control valve, it operates on a poppet-and-spring principle: when system pressure exceeds the set value, the poppet lifts off its seat, diverting excess flow to the tank port and thereby maintaining the desired working pressure. The “VB2” adjustment variant provides a defined pressure-setting mechanism, while the “4X” series designation indicates the current Rexroth component generation with standardized mounting dimensions. With a nominal pressure rating of 200 bar, this valve is engineered for reliable, repeatable pressure control in demanding hydraulic power units, manifolds, and machine tool systems.
