SMC Corporation VVFS3000-20A Speed Control Valve

The SMC VVFS3000-20A Speed Control Valve is an interface speed controller designed for use with the VFS3000 series of 4/5-port pilot-operated valves, throttling exhaust in the pilot circuit to set pneumatic cylinder travel speed. Available as two configurations, VVFS3000-20A-1 (Plug-in type) and VVFS3000-20A-2 (Non plug-in type), it works with VF(S/R)3000 valves to provide adjustable exhaust flow for precise speed control in automation systems. This accessory enables smoother start/stop and controlled motion in applications such as packaging, pick-and-place, and general manufacturing equipment, while preserving compact panel layouts by integrating with SMC’s VFS3000 ecosystem. Catalog notes across variants sometimes reference an exhaust-cleaner option, but the core function remains throttling exhaust to define actuator velocity, helping improve repeatability and reduce wear from abrupt velocity changes.
