Product Description

Rexroth R900409886 ZDB6VA2-42/200V

The Rexroth R900409886 ZDB6VA2-42/200V is a pilot-operated pressure relief valve in a sandwich plate design, engineered to protect hydraulic systems by limiting system pressure. It consists of a main valve assembly with a spool insert and a pilot control valve featuring a pressure adjustment element, typically a rotary knob with a scale. This model is configured for a maximum pressure setting of 200 bar and is equipped with FKM (Viton) seals, making it suitable for a variety of hydraulic fluids and operating temperatures. Its NG6 (CETOP 03) size and standardized ISO 4401 porting pattern facilitate straightforward installation in modular hydraulic systems and vertical stacking assemblies.
