Vic®-300 MasterSeal™ butterfly valves are designed for pressures ranging from full vacuum to 300 psi/2065 kPa and for bi-directional, dead end services to full working pressure. The valve features a patented seat design that assures full 360 deg sealing. The pressure enhanced seat compresses to form a larger seating area as the pressure increases. The seat design also contributes to the low breakaway torque capabilities of the MasterSeal™ valve. Valve construction and performance meet or exceed MSS-SP-67 requirements. Available in 2 to 12 in/50 to 300 mm sizes the valve is offered with a standard ISO mounting flange to accept most gear and power actuators. Vic-300 MasterSeal™ butterfly valves 2 to 6 in/50 to 150 mm are offered with a 10-position handle that may be configured for infinitely variable service with memory lock stop and is pad lockable. Sizes 8 in/200 mm valves are available with a lever lock handle that may be configured for infinitely variable service with memory stop and is padlockable. 2 to 12 in/50 - 300 mm sizes are available with a gear operator and can easily be configured into three way assemblies. Vic-300 MasterSeal™ butterfly valves accommodate 2 in/50 mm of insulation. An additional 2 in/50 mm neck extension is available when more than 2 in/50 mm of insulation is needed. A 4-1/2 in/120 mm long hand wheel input shaft extension is available for valve sizes 2 to 8 in/50 to 200 mm and a 3-1/2 in/90 mm long hand wheel input shaft extension is available for 10 to 12 in/25 to 300 mm valve sizes.
