VSFF Anti-Corrosive Solenoid Valve is a direct-acting solenoid valve designed specifically for chemically aggressive media. The valve body, internal flow path, and sealing surfaces are all made from PTFE (polytetrafluoroethylene), a material known for its near-universal chemical resistance. PTFE does not react with the vast majority of industrial chemicals, including concentrated acids, strong alkalis, oxidizing agents, and halogenated solvents, making it one of the few materials suitable for direct contact with these media.

Compared to metal-bodied solenoid valves with PTFE seals only, the VSFF eliminates any metal-to-media contact entirely. This is important in applications where even trace metal contamination is unacceptable, or where the media would corrode a valve body over time.
