Keystone Energy Tools is now the first drill pipe float valve manufacturer in the world certified to API Spec 7V.
Not the first American manufacturer. The first manufacturer, period.
To earn the license, our G-series and F-series valves passed a 7-step audit: hydro pressure, nitrogen seal at low and high pressure, 200 hours of slurry test with 2% sand content, a 100-cycle flow test, then a full repeat of the gas and hydro tests. No teardown allowed between stages.
Full breakdown of what the spec covers and why it matters:
