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.
