SMC VQC4300-5 Four Way Pneumatic Solenoid Valve

SMC VQC4300-5 is a 5-port plug-in, base-mounted pneumatic solenoid valve from the VQC4000 family, designed for four-way, three-position control with a closed-center neutral state. Driven by a 24 V DC coil, it is offered in two seal configurations: rubber-sealed VQC4300 and metal-sealed VQC4301, each with distinct flow characteristics to suit different leak-tolerance and durability needs. The valve features 3/8 inch porting for compact installations and is well suited to sequencing and directional control in automation lines, clamps, and double-acting cylinder circuits. Operating pressure for this class generally spans from 0.15 to 1 MPa, enabling reliable actuation across typical shop air systems. Flow performance varies by seal option, with Cv around 1.5 for the rubber-sealed variant and about 1.9 for the metal-sealed variant, supporting steady actuation at standard supply pressures. The base-mount, plug-in design simplifies replacement and integration within existing VQC4000 manifolds, making the VQC4300-5 a common choice where precise, energy-efficient pneumatic switching is required in factory automation, material handling, and machine tooling applications.
