Product Overview
The Rexroth ZDRY 10 VA6-11/315YV (Material No. 0811145190) is a direct-operated sandwich plate pressure reducing valve designed for precise secondary circuit pressure control in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve is part of the proven ZDR series and is engineered to maintain a constant reduced outlet pressure regardless of fluctuations in the primary system pressure or flow. The sandwich plate (sandwichplatte) design allows direct stacking between a directional control valve and its subplate, eliminating the need for additional piping and reducing installation footprint. The “YV” designation indicates an integrated pressure relief function on the secondary side, protecting the reduced pressure circuit from overpressure. With a nominal size of NG10 (CETOP 5 / ISO 4401-05) and a maximum primary pressure rating of 315 bar, this valve is ideally suited for demanding industrial applications requiring reliable, repeatable pressure reduction.
