Overview
The SMC VQ4201-5 is a compact 4/5-port solenoid valve from SMC’s VQ4000 series, engineered for base-mounted, plug-in installation in pneumatic control systems. This valve combines efficient operation with a robust design that supports cylinder actuation up to ø160 mm, making it ideal for automation equipment requiring high-speed, frequent switching with stable response characteristics.
Key Features
- IP65-compliant dust-tight, water-jet-proof protective structure
- Innovative mounting methods allow valves to be changed without entirely disassembling the manifold
- Built-in one-touch fittings save piping time and labor
- Ideal for applications requiring high speed, frequent operation, stable response time and long service life
- Power-saving design with low wattage coil options
- 100 million cycles service life per SMC specifications
