Product Overview
The Rexroth ZDBK 6 VB2-11=210V (Material Number: R900702156) is a direct-operated sandwich plate pressure relief valve engineered for precise system pressure limitation and protection within industrial hydraulic circuits. As part of the Rexroth ZDBK series, this valve is designed for sandwich plate mounting (module connection) in accordance with ISO 4401 / DIN 24340 size 6 (NG6 / CETOP 3) interface standards. The valve operates on a spring-loaded poppet or ball seat principle, opening proportionally when inlet pressure exceeds the adjustable set value, thereby diverting excess flow to the tank port and safeguarding downstream components from overpressure. The “VB2” designation indicates the pressure adjustment range and adjustment type, while the “210V” suffix denotes a maximum pressure setting of 210 bar. This valve is a critical safety and control element in manifold-based hydraulic power units, machine tools, and industrial press systems.
