Overview
The SMC VQ1201N-51 is a compact, 5-port pneumatic solenoid valve engineered for reliable, high-speed automation. This VQ1000 series valve features 5/2 configuration with solenoid/solenoid actuation and 24V DC coil voltage, making it ideal for industrial pneumatic control applications. The valve handles air or inert gas with an operating pressure range of 0.1–0.7 MPa (standard type), and its plug-in base-mount design simplifies system integration and component replacement.
Key Features
- Dual solenoid actuation with 2-position, double-acting configuration for reliable directional control
- Built-in one-touch fittings that save piping time and labour
- Innovative mounting methods allow valves to be changed without entirely disassembling the manifold
- Response time of 34 ms or less (rubber seal) ensures fast, consistent actuation
- Space-saving side-mounted solenoid and fittings for three-directional flexible installation
- No-screw, single-clamp assembly reduces reconfiguration labor
