Product Description

Rexroth Type Z2S Series Modular Pilot Operated Check Valves

Product Overview: The Z2S Series Modular Pilot Operated Check Valve is a critical component for achieving “zero-leakage” load holding in hydraulic systems. Featuring a standard sandwich plate design complying with ISO 4401 mounting standards, these valves are stacked directly beneath directional control valves. Their primary function is to provide a reliable seal for one or two actuator ports (A or B), preventing cylinder drift caused by pressure fluctuations or gravity loads.

This category features a full range of sizes from Z2S6 (NG6) and Z2S10 (NG10) to the high-flow Z2S16 (NG16), including specific parts like Z2S16-1-51, Z2S6-1-6X, and the Z2S10-1-3X/V with Viton seals.

Key Technical Advantages:

  • Absolute Sealing Integrity: Precision-ground and hardened poppets ensure a drop-tight metal-to-metal seal in the closed position, the premier choice for long-term pressure retention.

  • Decompression Capability: For high-pressure systems, specific pilot structures release pressure smoothly before full opening, eliminating hydraulic shocks and protecting system piping.

  • High-Temperature Configuration (V): Models like Z2S10-1-3X/V come standard with Viton (FKM) seals, suitable for phosphate ester fluids or high-temperature environments.

  • Compact Integration: The sandwich architecture eliminates complex external piping, significantly reducing the footprint and potential leak points of the hydraulic manifold.
