Flapper Pressure Test Valve
Flapper Pressure Test Valve from Metrol.
Flapper Pressure Test Valve from Metrol.
The FPT-V is designed to allow the tubing string to be pressure tested while running in the hole. The valve incorporates a flapper mechanicism that seats and seals when pressure is applied from above, but will float open against a retainer spring as the string is run in hole.
When the string is on depth and pressure testing is complete, pressure can be applied to the annulus to rupture a sheer disc and shift an internal mandrel to lock open the flapper.
