Valve Overview

Reverse flow check valves are the most reliable, first line of defense in protecting your swivel, standpipe, pumps and crew from the dangers of drill string kicks. It is specifically designed to be run through most BOP stacks as an integral part of the string when drilling through transitional zones or anytime a kick might be anticipated.

The unique top vent on the valve permits a partial flow-by of drilling fluids to make emergency stabbing faster and safer. The body of the valve is made from AISI 4145H modified fully heat treated steel alloy with a dart and seat specially designed to minimize the effects of mud cutting and washouts.
