SMC VQ4101-51 is a 5-port, 4-way, 2-position solenoid valve from the VQ4000 series, designed for base-mounted, plug-in installation in compact pneumatic circuits. It features a dust-proof housing and an aluminum spool with HNBR seals for durability in factory air systems, and it is actuated by a single 24 V DC solenoid with a light/surge voltage suppressor for transient protection. Rated for supply pressures from 0.15 to 1 MPa, it directly directs compressed air to actuators and cylinders, making it a common choice for automation lines in packaging, manufacturing, and machine tooling.
