SMC VFS2220 5 Pneumatic Solenoid Directional Valve

SMC VFS2220 is a five-port, two-position pilot-operated pneumatic valve engineered for precise, rapid direction control of compressed air in automation systems. It belongs to the VFS2000 family and is offered in variants with metal-seal construction and body-ported architecture, designed to switch between the P port and A/B cylinder paths while venting through R1/R2. Coil voltages vary by model, with DC24V and 110 VAC options commonly available, allowing selection to suit control panels and regional power standards. Performance data cited for this line include a flow coefficient (Cv) around 0.9 for P→A/B, a maximum operating cycle near 1200 cycles per minute, and a weight near 0.87 lb (about 0.39 kg); operating temperature spans roughly 14–140 °F (-10 to 60 °C). Port connections in many versions are 1/4" BSPT (with variations by region), and the valve is designed for mounting to manifolds or direct piping in compact automation cells. Typical applications include powering or releasing double-acting pneumatic cylinders in packaging, machining, and general manufacturing environments where reliable, fast-air control is essential.
