SMC Corporation VFS3320-3DZ-03N Solenoid Valve

SMC VFS3320-3DZ-03N is a 5-port pilot-operated solenoid valve from the VFS3000 series, designed for compact, closed-center pneumatic control in automation systems. The valve configuration is closed-center, with Rc port options in 1/4" and 3/8" to fit small manifolds and tight installations. Flow characteristics provide Cv values of about 1.1 for Rc 1/4" and 1.6 for Rc 3/8", enabling solid actuation while maintaining low leakage when centered. Coil options include 24 VDC and 100/200 VAC (50/60 Hz), with inrush power around 5.6 VA (50 Hz) / 5.0 VA (60 Hz) and holding power near 3.4 VA (2.1 W) / 2.3 VA (1.5 W) for the respective frequencies. The 1/4" Rc variant is specified for up to roughly 600 cycles per minute, with a response time of 40 ms or less, making it suitable for repeatable, precise sequencing in pneumatic circuits. Built with a metal-seal, body-ported construction, it is intended to minimize package footprint while delivering reliable springless operation in automation lines. As part of the VFS3000 family, the VFS3320-3DZ-03N supports standard coil voltages and common pneumatically driven applications, such as actuating cylinders, valve manifolds, and other pneumatic devices in production environments.
