Rexroth Type Z2S Series Sandwich Plate Pilot Operated Check Valves

Product Overview: The Z2S Series Pilot Operated Check Valve is a cornerstone for ensuring precise positioning and load-holding of hydraulic actuators. Designed as a sandwich plate valve, it can be mounted directly under the directional valve, significantly reducing the system’s footprint. It allows free flow in one direction and absolute shut-off in the opposite direction, which can only be opened when pilot pressure is applied.

This series includes the complete range from Z2S6 (Size 6) to Z2S22 (Size 22), featuring popular models like Z2S6-2-6X and specific part numbers such as R900347496. It is the premier choice for CNC machine tools, die-casting machines, injection molding equipment, and heavy-duty lifting load-holding circuits.

Key Technical Advantages:

• Zero-Leakage Integrity: Hardened precision poppets and seats guarantee zero internal leakage during long-term pressure holding, preventing unwanted actuator drift.

• Sandwich Plate Design: Complies with ISO 4401 mounting standards, allowing for the vertical stacking of multiple hydraulic functions to simplify piping and installation.

• Variable Cracking Pressures: Available with different built-in spring options to ensure smooth operation across various complex hydraulic environments.

• Heavy-Duty Durability: Rated for operating pressures up to 315 Bar (31.5 MPa), capable of withstanding the most demanding industrial duty cycles.
