Drill pipe float valves are one-way safety valves that stop drilling fluid from flowing back into the drill string when making and breaking connections.

Keystone makes nine models split into plunger types for instant, economical shutoff and flapper types for full-flow, abrasive, and high-pressure wells.

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.
