Product Overview
The HAWE SK7922-3/6F directional seat valve (material number 257525 010) is a directly actuated, poppet-type directional valve manufactured by HAWE Hydraulik, engineered for leak-free load holding and precise switching of hydraulic flow paths in high-pressure industrial circuits. Unlike spool-type directional valves, the SK series uses a seated (poppet) design that provides zero internal leakage in the closed position, making it the preferred solution wherever drift-free load retention, pressure holding, or safe blocking of actuators is mandatory. The valve is actuated via a mechanical lever or cam, with the seat-and-poppet working principle ensuring fast, positive response and high resistance to contamination. Its compact 6-size (NG6 / CETOP 3) footprint allows direct manifold or subplate mounting, integrating seamlessly into clamping systems, test rigs, and safety-related hydraulic circuits.

Engineering Features & Advantages
- Zero-Leakage Sealing: The seated poppet design eliminates internal leakage in the blocked position, guaranteeing drift-free load holding and reliable pressure retention in clamping and safety circuits.
- High-Pressure Capability: Engineered for the HAWE high-pressure range up to 400 bar, delivering dependable switching performance in demanding industrial hydraulic systems.
- Contamination Tolerant: The seat-and-poppet working principle is significantly less sensitive to particulate contamination than close-tolerance spool valves, reducing downtime and maintenance cost.
- Fast, Positive Response: Direct mechanical actuation provides immediate, defined switching behavior without pilot-oil dependency.
- 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.
