Product Overview
The Rexroth ZDB 10 VA2-4X/315V (Material No. R900409955) is a direct-operated pressure relief valve from the proven ZDB series, designed in a sandwich (stack) plate configuration for manifold and subplate mounting. As a pilot-operated pressure control valve, it limits system pressure by diverting excess flow to the tank when the preset cracking pressure is reached, thereby protecting downstream components and maintaining stable circuit conditions. The “VA2” designation indicates a pressure adjustment element with a specific adjustment range, while the “315V” code denotes a nominal pressure rating of 315 bar with a Viton (FKM) seal compound for enhanced fluid and temperature compatibility. This valve is engineered for precise, repeatable pressure regulation in demanding industrial hydraulic systems.

Engineering Features & Advantages
- Precision Pressure Regulation: The direct-operated pilot stage delivers accurate, repeatable cracking and reseat behavior, minimizing pressure overshoot and ensuring stable system pressure across the full adjustment range.
- High-Pressure Capability: Rated for continuous service up to 315 bar, suitable for high-pressure industrial circuits requiring reliable overpressure protection.
- Viton (FKM) Sealing: The “V” suffix indicates FKM seals, providing superior resistance to elevated temperatures and aggressive hydraulic fluids compared to standard NBR compounds.
- Sandwich Plate Design: Compact NG10 stack-mounting configuration enables space-saving integration into modular manifold assemblies without additional piping.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with robust internal components and proven Rexroth manufacturing quality.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Rexroth ZDB series specifications, ensuring drop-in interchangeability.
