Victaulic expanded its Vic®-300 MasterSeal™ butterfly valve line with a completely stainless steel option. The company says the new Series 461 stainless steel butterfly valve provides a cost-competitive option for the HVAC and potable water markets. The Series 461 valve is NSF 61/372 approved to meet the new low-lead requirements, and is rated for cold and hot potable water service. Series 461 valves are designed for pressures ranging from full vacuum to 300 psi (2,065 kPa) and for bi-directional, dead-end services to full working pressure. The stainless steel valve features a patented seat design featured on the Victaulic Series 761 butterfly valve, which assures full 360-degree sealing. The valves are available in 3- to 8-in sizes.
