The Festo 18980 (type VIFB‑03‑B) is a modular, fieldbus-capable valve terminal (type 03 series) designed for pneumatic automation systems. It supports up to 26 valve stations, 3 pressure zones, and integrates pilot air supply and exhaust controls within an IP65-rated housing. Suited for PROFIBUS or comparable fieldbus modules, this valve terminal is discontinued (last available ~2012) but remains functionally relevant for legacy systems.

Key Features:

• Model: VIFB‑03‑B (P/N 18980)

• Valve Configurations: 5/2 bistable, 5/2 monostable, 5/3 pressurised, 5/3 exhausted, or 5/3 closed

• Nominal Flow: 300–1300 L/min (per station)

• Operating Pressure: –0.9 to 10 bar; internal pilot supply at 4–8 bar

• Valve Positions: Up to 26 stations; supports 3 distinct pressure zones

• Fieldbus Integration: Equipped for fieldbus interfacing (e.g., PROFIBUS modules)

• Environmental Specs: IP65, ambient –5 to +50 °C

• Dimensions: 18–26 mm width per station, widths vary by configuration

• Exhaust Ports: Throttleable integrated exhaust-air control
