Float Valve Overview

Valve Body
Oteco valve bodies are manufactured for today's increasingly harsh drilling environment. All valve bodies are cast out of ductile iron or a low-alloy carbon steel and are heat treated to a hardness equal to or less than 22 Rockwell C (£ 22 Rockwell C 2 HR) to address the corrosive effects of hydrogen sulfide gas (H2S). Oteco's integral valve bodies are manufactured from a one-piece casting and are not welded together the way some other competitors produce their bodies. This means that you receive a superior and more reliable valve body.

Integral Plunger
Valves All of Oteco's plunger valves are machined from one solid piece of material to produce a more reliable float valve and reduce the risk of downhole valve failure. Other leading manufacturers use two separate pieces of material to construct their plungers, which are invariably either shrunk fit, screwed or welded together.

Flapper Valves
All Oteco 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), hydrogenated nitrile butadiene (HNBR) and Viton� (fluoroelastomer, FKM).

Inconel� springs come standard on all our valves. Inconel� springs are significantly more resistant to corrosion when compared with the standard service springs provided by most other manufacturers. Inconel� springs are also good for sour-gas (H2S) applications.

All Oteco drill-pipe float valves and replacement parts are manufactured to standard industry dimensions and are interchangeable with other major manufacturer's parts.

Sour-Gas (H2S) Service Available in both F and G models.
