Keystone provides Certified, Pressure-Tested Drill Pipe Float Valves. As a leading manufacturer of DP float valves, we know the severity of drilling with a reliable and trusted float valve; therefore, we offer certified float valves that are serialized. Additionally, we will provide certification of high-and-low pressure tests upon request.
We proudly produces one of the most reliable Drill Pipe Float Valves on the market today. They 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.
H2S / High Temp. Float Valves are available in Model F and Model G.
Low-and-High-Pressure Test Charts are available upon request.

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.
For highly corrosive environments we offer stainless steel & Nickle Plated 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.
Our standard-service flapper valves are made of low-alloy steel and then case hardened for wear resistance, thus giving a longer operating life.
Available elastomers are nitrile butadiene (NBR, Buna-N) and Viton® (fluoroelastomer, FKM)(H2S Applications) and Aflas (steam service)
*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
* Steam Service Aflas (475 Deg. F.) Temp rating
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.
All Keystone drill pipe float valves and replacement parts are manufactured to standard industry dimensions, and are interchangeable with other major manufacturers’ parts.
Available in both F and G models.
Standard valves – 7,500 PSI working pressure
High-pressure valves – 10,000 PSI working pressure
