Specification

Drill Pipe Float Valves - Check Valves
For all diameters of drill rods
Our complete line of Float Valves and repair kits can accommodate a wide range of drilling situations and operating conditions. The Baker SPD Model F Plunger type valve offers positive and instant shut-off against high or low pressure, assuring continuous control of fluid flow during drilling. The fast-acting plunger valve eliminates breakage of wet joints.

*Made of low carbon steel suitable for most applications
*Parts are interchangeable with Baker style equipment
*Provide added blowout protection at the bottom of the drill
*Prevent flow-back when adding joints and bit plugging while making connections

This Drill Pipe Float Valve is normally installed in a standard bore-back of the bit sub, to provide fluid flow control at the bottom of the drill stem. It also prevents backflow of cuttings from plugging the drill bit jets while making connections.
