Cartridge Valves

These valves push the envelope of higher pressures and temperatures while successfully operating in both clean and corrosive, debris laden fluids tested to date.


Building on the Gilmore pedigree in wireline tool sampling valves and the proven line of drilling control valves with over a half century of experience, we have engineered a reliable line of downhole solutions for a variety of tool applications in drilling and measurements, rotary steerable and smart completions.
