The Flow Activated Valve (FAV) is a valve designed to be run open to enable high rate circulation / displacement in the reverse direction.
The valve is closed by increasing the flow rate through the unit to above a predetermined value. Alternatively, the FAV can be closed by dropping a ball to land on a ball seat and applying pressure. Either way will create a positive differential pressure over the valve. A changeable orifice can adjust the flow rate limits required for closing.
After the FAV has closed, the valve provides a tested and qualified barrier in accordance with ISO 14310:2008 V0 up to 345 bar at 4-60 C
Product Features
•ISO Vo qualified: 345 bar, 4-60 C
•Adjustable closing flowrate
•Adjustable sizes
•Adaptable to different packers by using an interface
•Resistant to closing in an event of reverse flow to kill the well
•Optional ball drop closure
