High Flow Screw Type Coupling
VIV1 Series
Features and Benefits
Applications
• Large bore coupling
• Hydraulic return lines and medium pressure lines
• High flow rates up to 525 GPM
• Low pressure diesel supply lines
• Working pressures from 2,200 to 3,000 PSI
• Applications needing large bore couplings with high
flow rates
• Can connect under residual pressure
