BT-DPFV F/FA G/GA series Float Valve
Forum Baker SPD F & G style Float Valve with alloy steel
BETTER provides Float Valves, Repair Kits, Baffle Plates and Puller
Assembly Tools, including H2S and high temperature service
condition. These Drill Pipe Float Valve provides added blowout
protection at the bottom of the drillstring, prevent flowback when
joints are added, and keep cuttings out of drill pipes to prevent
bit plugging while making connections.
- All BETTER Float Valves are manufactured with alloy steel integral
- All Flappers are investment cast and then case hardened for wear
- Elastomers available Buna-N/NBR (Standard), Viton/FKM (Hi-Temp),
HNBR (H2S) for optional.
- All BETTER Float Valves, baffle plates, and valve pullers are
interchangeable with the Baker Style Model F/FA, and Baker Style
Model G/GA Float Valves.
- Heat Treatment: Carburize at 1500-1550°F to .005/.010 depth with
hardness 58 HRC Min.
- Surface treatment: Xylan fluoropolymer coating with depth
0.25-0.30mm or Nicked Plated.
- Standard API NRV
- Color Blue or Black, or customized
Model F Plunger Type Float Valve
Model F DPFV provides positive and instantaneous shut off against
high and low pressure, assuring continuous control of fluid during
drilling, including H2S application. For normal drilling
operations, the durable Model F is the most economical choice and
is available in all sizes.
BETTER Model F Drill Pipe Float Valve is made of alloy steel body
and dimensionally identical to the standard Baker F Float Valve,
interchangeable trim, recommended for use with downhole mud motors.
Model FA Drill Pipe Float Valve
Model FA DPFV offers all the standard feature of Model F with the
added feature of a port which allow a fluid path through the
valve’s center. It is recommend to use for monitoring the bit head
when differential pressure required. Available in all sizes.
Model G Flapper Type Full Open Valve
It is good for use with highly abrasive fluids, with flapper design
to open 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; and open when the first joint is raised out of
the hole assuring the first joints drain and are not pulled wet.
All flappers for Model G are made of low alloy steel 8620 with QPQ
treatment to resist wear and erosion. The flapper valve opens fully
during circulation providing an unrestricted flow for drilling
Model GA Differential Pressure Monitoring Valve
It is identical to Model G except of a hardeneddiameter tungsten
carbide orifice bean insert in the flapper to provide automatic
partial filling of the drill pipe during running in, which is used
to monitor the bit head when differential pressure required.
