Product Overview
The Rexroth ZDC 10 P-25/M (Material Number R900488023) is a pilot operated check valve designed for leak-free load holding and controlled flow blocking in hydraulic systems. As part of the Rexroth ZDC series, this valve is a sandwich (modular) plate design that mounts between a directional control valve and its subplate, providing a compact and space-saving solution for preventing reverse flow until a pilot pressure signal is applied. The valve features a poppet-type seating design that ensures zero leakage in the blocked direction, making it ideal for applications requiring precise load holding, such as clamping circuits, cylinder locking, and safety-related hydraulic functions. The “P” designation indicates the pilot port configuration, while “25” refers to the nominal flow capacity. With its robust construction and precision-engineered sealing surfaces, the ZDC 10 P-25/M delivers reliable performance in demanding industrial environments.

Engineering Features & Advantages
- Precision Performance: Poppet-type seating ensures zero internal leakage in the blocked direction, providing reliable load holding and preventing drift in cylinder circuits.
- Pilot Operated Release: Allows controlled opening of the check valve via external pilot pressure, enabling bidirectional flow when required while maintaining leak-free blocking when pilot pressure is removed.
- Modular Sandwich Design: Compact ISO 4401-05 / CETOP 5 interface allows direct mounting between directional valves and subplates, reducing piping complexity and installation time.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and precision-machined sealing surfaces for long service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification.
Typical Industrial Applications
