Master Flo Valve, Inc.

Master Flo Valve Inc. is an API-licensed manufacturer of choke valves in Edmonton, Canada, with product installed around the globe. The 40,000-square-foot Houston manufacturing plant provides land, offshore and subsea products and services for the United States market and is Master Flo’s center of excellence for subsea engineering and design.

Chokes are highly specialized valves designed to maintain control of pressure and flow in oil and gas production, drilling and fracking operations as well as prevention and containment of well blowouts. Applications range from pressures as high as 20,000 PSI and temperatures approaching 500°F down to cryogenic levels. As such, Master Flo’s chokes are critical not only to operator success, but in protecting the health and safety of oilfield personnel and the environment.

Master Flo is proud of its reputation for quality and performance, and the new facility boasts state-of-the-art equipment to support that legacy. Capabilities include 3D modeling and prototyping, flow testing, subsea integration testing, API qualification testing, hyperbaric testing, advanced quality control inspection equipment and maintenance of customer assets.

Master Flo, together with parent company Stream-Flo, has now opened a second facility at 9715 Derrington dedicated solely to industry training. The facility boasts state-of-the-art equipment and functional displays combined with classroom-style education programs designed to enhance industry understanding around the purpose, design, and operation of oilfield equipment.
