GF Piping Systems’ 5-series, Type-578 Lug Style Butterfly Valves are now available and offer excellent corrosion resistance with long service life.
They are offered in manual, electric and pneumatic actuated versions. Constructed of a glass-filled polypropylene outer housing with over-molded SS316 lugs, the valve incorporates a unique industry-tested, double-eccentric design that allows the disc to completely disengage from the seal during operation, reducing friction and component wear to provide longer service life. The valve is available in PVC, CPVC, PP, ABS, and PVDF in sizes from 2″ to 12″ with seal material choices of EPDM, FPM and PTFE.
