1. Spool-type structure with superior sealing performance and instant response characteristics;
2. Double pilot operation enables position memory function;
3. Precision-machined internal bores ensure minimized friction resistance, low actuation pressure (0.15MPa), and extended service life;
4. Maintenance-free operation without lubrication requirements;
5. Multiple mounting orientations (X/Y/Z axes) for flexible installation;
6. Compatible with manifold base integration for space-optimized valve arrangements.
