Product Overview
The Rexroth ZDB6VA2-4X/315V (Material No. R900409893) is a direct-operated pressure relief valve from the proven ZDB6 series, designed in a sandwich plate (stack) configuration for manifold and subplate mounting. As a pilot-operated pressure control valve, it limits system pressure by diverting excess flow to the tank circuit once the set pressure is reached, thereby protecting downstream components from overpressure. The “VA2” designation indicates a specific pressure adjustment and adjustment element configuration, while the “315V” rating confirms a maximum working pressure of 315 bar. This valve is engineered for precise pressure regulation in demanding industrial hydraulic systems, offering reliable response and low-pressure override characteristics.
