Keystone Drill Pipe Float Valves

Keystone Energy Tools proudly produces one of the most reliable Drill Pipe Float Valves on the market today. Our float valves are designed with the latest in 3D Modeling, allowing for a better mating of component parts. This in turn reduces the risk of down hole valve failure. Drill pipe float valves are essential for drilling, and must stand the test of harsh environments. Our valves are precision manufactured from high-grade materials and perform optimally in drilling environments. We offer valves for all drilling applications.

All KET Float Valves, baffle plates, and valve pullers are interchangeable with the Baker® Style Model F, and Baker® Style Model G Float Valves.

Pressure Tested Float Valves

Low and High Pressure Test Charts are available upon request.

Cages

Our cages are manufactured for today’s increasingly harsh drilling environment. The cages are cast out of alloy steel and are heat treated to a hardness equal to or less than 22 Rockwell C (≤ 22 Rockwell C 2 HR). Heat treating the valves address the corrosive effects of hydrogen-sulfide gas (H2S) on them. Keystone’s integral valve bodies are manufactured from one-piece casting and are not welded together, contrary to the way some competitors produce theirs. This means that you receive a superior and more reliable valve body.

*Stainless steel valve bodies are available upon request.

Integral Plunger Valves

All plunger valves are machined from one solid piece of material, producing a more reliable float valve and reducing the risk of down hole valve failure. Other leading manufacturers construct their plungers from two separate pieces of material. This produces plungers that are invariably either shrunk fit, screwed, or welded together.

Flapper Valves

Our standard-service flapper valves are made of low-alloy steel and then case hardened for wear resistance, thus giving a longer operating life.

Elastomers

Available elastomers are nitrile butadiene (NBR, Buna-N) and Viton® (fluoroelastomer, FKM)(H2S Applications)

*Standard Service Buna Nitrile (212 Deg F) Temperature Rating

*Hi-Temp Viton (450 Deg F) Temperature Rating

* H2s Service Viton (450 Deg F)    Temperature Rating

*Hi-Temp H2S Viton (450 Deg F) Temperature Rating

Springs

Elgiloy, Inconel® or stainless steel springs come standard on all our valves. These high alloy springs are good for sour gas (H2S) applications. KET springs are significantly more resistant to corrosion in comparison to standard-service springs provided by most other manufacturers.

Interchangeability

All Keystone drill pipe float valves and replacement parts are manufactured to standard industry dimensions, and are interchangeable with other major manufacturers’ parts.

H2S/High Temp. Service Float Valves

Available in both F and G models.

Operating Pressure

Standard valves – 7,500 PSI working pressure

High pressure valves – 10,000 PSI working pressure

Keystone offers both Plunger-Type Float Valves and Flapper-Type Float Valves.
