SMC VQC4400-51 Solenoid Actuator

SMC VQC4400-51 is a five‑port, three‑position base‑mounted solenoid valve in the VQC4000 family, designed for compact, plug‑in installation with exhaust center‑side porting. This single‑unit valve (plug‑in) supports standard compressed air operation from 0.15 to 1 MPa and delivers a Cv in the mid‑range (about 1.5–1.7) to reliably actuate pneumatic circuits. The VQC4400‑51 includes a light/surge voltage suppressor for coil protection and is built for base‑mounted use on manifolds or subplates, enabling quick field replacement. With P, A, B, EA, and EB ports and a 5/3 configuration, it can control single‑ or double‑acting cylinders in common automation tasks such as pick‑and‑place, clamping, and sequencing on manufacturing lines. The valve’s base‑mounted, plug‑in form and center‑side exhaust layout simplify piping and installation in tight spaces, while remaining compatible with standard base plates and subplates for modular systems. Durability is a hallmark of the VQC4000 series, with SMC advertising a long service life under appropriate life‑test conditions, including high‑cycle operation. This model is suitable for industrial environments where reliable, compact pneumatic control is required and where exhaust routing and plug‑in replacement are important for maintenance and uptime.
