FLOAT VALVES

The Float Valve provides positive and instantaneous shut-off in both high and low pressure conditions, ensuring continuous control of fluid flow during drilling. The Plunger-Type Float Valve provides added blowout protection at the bottom of the drill string, prevents flowback when joints are added, and keeps cuttings out of the drill pipe to prevent bit plugging while making connections. This float valve is recommended for use with downhole mud motors.

The Flapper-Type Float Valve incorporates a specially designed flapper which opens quickly and fully to provide a completely unrestricted bore through the valve. When circulation stops, the flapper closes instantly to prevent cuttings from entering the drill string and plugging the bit. The valve opens when the first joint is raised out of the hole ensuring proper drainage, so the joints are not pulled wet.
