Float Valve Model F And G - China

price: contact company for price

Float (check) valve is usually installed in float subs (long

subs bored out for a specific float) and prevent fluids from

backing up in your drill string while adding/removing rods.

The type available of float valve as below:

Model F (plunger valve):Instantaneous shut off against high

or low pressure, assuring continuous control of fluid flow

during drilling.

Model FC (Automatic Fill valve) Automatic feature allows

drill pipe to fill from the bottom, removing the mess,

hazards, and lost time from filing. When running in the

hole, automatic fill feature eliminates the ‘ram effect’

preventing the down hole pressure surges that can cause

formation damage.

Model G (Full open valve, flapper type):When circulation

stops, flapper closes instantly to prevent cuttings from

entering drill string and plugging bit. Valve opens when the

first joint is raised out of hole assuring the first joints

drain and are not pulled wet. Saves mud and avoids safety

hazard and downtime.

Model GA (Differential Pressure Monitoring Valve):Hardened

1/4in. diameter tungsten carbide orifice bean insert in

flapper to provide automatic partial filling of drill pipe

during running in.

Model GC (Automatic Fill Flapper Valve)Uses low carbon steel

“automatic fill” key assembly that allows pipe to fill

from bottom.

Model GCA (Automatic Fill with differential pressure

monitoring valve)Incorporate both GC and GA

Model GS (non-ported flapper) and GAS (ported flapper)For

high flow and erosion resistance,

made of alloy steel and unique flapper relief to reduce

flapper spring and pin wear. Option to have tungsten carbide

coating on flapper face.
