To conquer the big challenges,
start with the small ones
Precision-machined drill pipe float valves from RoNal are a good place to start
Enhanced Economics and Reduced Risk from a Superior Float Valve
RoNal high-quality, competitively priced drill pipe float valves offer a superior alternative to conventional cast products. Carefully machined using 4140-HT heat-treated material, these field-proven valves have a significantly longer service life. RoNal float valves can be easily rebuilt using our convenient repair kits. You can use our valves over and over with confidence. Durability and extended service life also means less risk of broken parts damaging the motor and creating problems with other BHA components. A superior product at a competitive price with long-term benefits, RoNal drill pipe float valves provide performance and economics that add up.
Valves and Repair Kits
Built for extreme environment service.
RoNal float valves are precision-machined from 4140-HT heat-treated metal for the same rugged dependability as the sub in which they are placed. Viton® Seals, standard on models 4R and smaller, further ensure a long service life in extreme environments. The seals are rated for constant 400F (204C) service. In addition, RoNal float valves feature stainless steel springs to enhance service life.
Broad range of application.
RoNal float valves are available for a broad range of service applications with six models in nine sizes (1R to 5F-6R).
Model F Plunger
Model FGAC
Features a center-drilled piston to allow filing above the valve to manage hydrostatic pressure in directional drilling applications.
Model FGA
Features a tungsten carbide port to allow filing above the valve to manage hydrostatic pressure in directional drilling applications.
Model G Flapper
Model GA Ported Flapper
Features a tungsten carbide port to allow filing above the valve to manage hydrostatic pressure in directional drilling applications.
Model FBP
Features an integrated baffle plate for landing instrument packages.
Repair Kits Allow for Easy Redress in the field
For long service life, RoNal float valves are easily rebuilt using our repair kits. Each rubber kit includes parts to rebuild two valves; each metal kit includes parts to rebuild one valve.
