PTFE Bellows Solenoid Valve Prevents Fugitive Emissions


Plast-O-Matic Valves, Inc. announces a new all-purpose PTFE Bellows Solenoid Valve which 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. The valve employs the patented Plast-O-Matic Fail-Dry® safety design feature which provides visual warning of any seal failure while allowing the valve system to continue operation and avoiding costly shut-downs. Piping connections in sizes 1/4” - 1” are offered in PVC, CPVC, Polypropylene, and PVDF (Kynar®) .
