Overview

The SMC VQ4201-5 is a 2-position double solenoid valve from SMC's VQ4000 series. VQ valves are ideal for applications requiring high speed, frequent operation, stable response time and long service life. Innovative mounting methods allow valves to be changed without entirely disassembling the manifold. This base-mounted design operates on compressed air or inert gas, making it suitable for diverse automation environments where compact installation and reliable actuation are critical.
