Product Overview
The HAWE GR 2-12S is a directly actuated directional seat valve engineered by HAWE Hydraulik, a globally recognized manufacturer of compact hydraulic components. Operating on the proven seat valve principle, this 2/2-way valve uses a spring-loaded ball or cone seat to provide zero-leakage shut-off in the closed position, making it fundamentally different from spool-type directional valves. The GR series is designed for leak-free load holding, clamping, and pressure isolation duties in hydraulic circuits where even minimal internal leakage is unacceptable. With a nominal size of 12 (NG 12) and a maximum operating pressure of up to 400 bar, the GR 2-12S delivers reliable, wear-resistant switching performance in demanding industrial and mobile hydraulic systems.

Engineering Features & Advantages
- Zero-Leakage Sealing: The seat valve design (ball/cone on hardened seat) guarantees absolutely tight shut-off in the blocked direction, preventing load drift and pressure loss in holding circuits — a decisive advantage over conventional spool valves.
- High Pressure Capability: Rated for continuous service up to 400 bar, suitable for high-pressure clamping, press, and load-holding applications.
- Compact Cartridge Construction: Space-saving design enables direct integration into manifold blocks and custom hydraulic power units, reducing piping and potential leak points.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Precision-manufactured to original HAWE specifications for direct replacement, minimising downtime and eliminating fitment issues.
