SMC VQC4400-51 Pneumatic Solenoid Valve System

SMC VQC4400-51 is a 5-port, 3-position pneumatic solenoid valve in the VQC4000 family, designed for base-mounted, plug-in installation on manifolds as a single, compact valve unit in modular blocks. It features an exhaust-center, side-ported configuration with a metal seal and an integrated LED indicator plus surge‑voltage suppressor for clear feedback and electrical protection in dense control panels. Rated for clean compressed-air service from 0.15 to 1 MPa, it delivers a flow of 1.5 to 1.7 Cv and is suitable for actuating pneumatic cylinders and other loads in automation circuits, whether used as a standalone valve or as part of a base-mounted manifold assembly. The VQC4000 series emphasizes longevity, with SMC noting a long service life of up to 100 million cycles for this valve family, making the VQC4400-51 a robust choice for high-demand, high-cycle applications.
