Product Description

Rexroth R900421985 Z2S10-2-3X/

The Rexroth R900421985 Z2S10-2-3X/ is a pilot-operated check valve designed in a sandwich plate configuration. This valve type Z2S is specifically a double check valve, meaning it provides leakage-free blocking of flow in one direction for two ports (A and B) and allows free flow in the opposite direction. It is pilot-operated, allowing the check function to be overridden by a pilot pressure signal. The Z2S10 series is designed for vertical stacking assemblies and conforms to ISO 4401 porting patterns, making it suitable for various industrial hydraulic applications where reliable load holding or circuit isolation is required.
