Flapper Pressure Test Valve

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.

Features & Benefits

  • Enables self-fill of DST string
  • Unrestricted ID once tool is locked open
  • Withstands high differential across flapper
  • Suitable for high deviation
  • Suitable for DST, integrity tests & flex trips
  • Field replaceable rupture disc
