This all-purpose PTFE Bellows Solenoid Valve eliminates leaking of fugitive emissions to the atmosphere. A significant break-through in environmental safety, these thermoplastic valves can also be used with virtually all types of fluids, including acids, caustics, solvents, and chlorine solutions, as well as ultra-pure liquid applications. The major distinguishing feature of this unique valve is a PTFE bellows, barrier-type, dynamic seal which replaces the elastomer packing of conventional valves. The bellows flex to provide bubble-tight sealing of hazardous fluids, and since PTFE is not subject to chemical attack, exceptional performance and working life of over 2,000,000 cycles is normal.
