Drill Pipe
Float Valves

The Baker® drill pipe float valve was THE float valve of choice for many years - That’s who originated it and built it first.

By the 1990s, a few other oilfield tools manufacturers started making them. But for many, the Baker® brand was the only one they would use, and Baker® SPD was considered to be the leading manufacturer of drill pipe float valves in the industry. In 2006 Baker Hughes® sold off Baker SPD® and quit making Float Valves.

So there is an education gap there, and we find ourselves explaining to the customer that there IS no Baker® drill pipe float valve any longer.

But there’s good news. The Baker® brand was well-loved due to its quality production and superior engineering, construction, and dependability. And today that quality has been matched—and exceeded— with the Keystone Energy Tools line of float valves. 

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 & Nickel 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
