Overview
The SMC VQ1301N-51 is a high-performance 5 port solenoid valve optimized for pneumatic automation applications. This plug-in style valve features a 3 position closed center spool mechanism with dual solenoids for precise directional control. The screwless, one-clamp mounting structure enables fast valve replacement without dismantling the entire manifold—a critical advantage for maintenance and system downtime reduction.
Key Features
- 5 Port Configuration: Operating pressure range 0.1–0.7 MPa (high pressure style 1.0 MPa)
