Stream Flo Industries

What Stream Flo Industries does

Stream-Flo Industries Ltd. is a privately-held, family-owned (McNeill family) manufacturer of wellhead and pipeline pressure control equipment for the global energy industry, founded in 1962 and headquartered in Edmonton, Alberta, Canada. The company designs and builds API-monogrammed wellheads, gate valves, check valves, and Crown-Fusion trunnion and floating ball valves rated for pressures from 2,000 to 20,000 psi and temperatures from -75°F to 650°F, along with electro-hydraulic and self-contained hydraulic actuated valve systems, including the SmartVue-powered ESD-EHX intelligent valve controller. Its product line covers conventional, thermal/SAGD, custom-engineered, and space/time-saving wellhead configurations, plus bundled Config2/ESD+ systems that combine Stream-Flo actuated safety valves with Master Flo choke valves.

The company operates as the parent of the Stream-Flo Group, which includes Master Flo Valve Inc. (choke valves and flow management) and Dycor Technologies Inc. (data acquisition and automation, acquired 2017). Revenue is generated through direct enterprise field sales of manufactured hardware, aftermarket services (installation, maintenance, frac support, valve servicing), equipment rental, and customer property management, supported by a service network of more than 22 locations across Western Canada and the United States and a fleet of 100+ GPS-equipped service units providing 24/7 technical support. Pricing is quote-based and not publicly disclosed, and customer relationships are anchored in long-term partnerships with oil and gas producers operating in Western Canadian, US Permian, and selected international plays, with emerging exposure to CCUS, geothermal, hydrogen, and lithium extraction applications under a recently launched Decarbonization Solutions line.
