Product Overview
The Rexroth SV6PB1-62 (Material Number: R900494086) is a pilot-operated check valve from the proven SV series, designed for leak-free load holding and controlled flow in industrial hydraulic systems. As a modular sandwich-style component, it blocks flow in one direction until a pilot pressure signal is applied to open the poppet, allowing reverse flow. This design makes it ideal for load-holding circuits, cylinder locking, and preventing drift in vertical or clamping applications. The valve is engineered for direct integration into standardized modular valve stacks, ensuring reliable sealing and precise pilot actuation in demanding hydraulic circuits.

Engineering Features & Advantages
- Precision Performance: Poppet-type design ensures zero leakage in the blocked direction, providing reliable load holding and preventing cylinder drift.
- Pilot-Operated Control: Allows reverse flow only when pilot pressure is applied, enabling controlled lowering or retraction of actuators.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and high cycle life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, including the standardized NG6 modular interface.
- Modular Integration: Designed for sandwich mounting in valve stacks, simplifying system assembly and reducing piping complexity.
Typical Industrial Applications
This pilot-operated check valve is commonly used in plastic injection molding machines, metallurgical presses, construction and marine hydraulics, and CNC machine tools. It is particularly suited for load-holding circuits, clamping systems, and any application requiring leak-free blocking and controlled release of hydraulic actuators.
