High-precision hydraulic control valves engineered to AWWA standards, optimized for pressure and level regulation in Canadian pipelines.
Canada’s water distribution and industrial infrastructure operate under some of the most challenging conditions globally. Spanning vast geographic regions, municipal distribution systems must manage extreme seasonal temperature drops, preventing freezing while regulating varying pressure zones across hilly terrains like British Columbia or the expansive plains of Alberta and Saskatchewan.
Under provincial regulations and standards such as NSF/ANSI 61 for drinking water safety and the American Water Works Association (AWWA) design parameters, Canadian engineers prioritize long-term durability, structural integrity, and corrosion resistance. Key priorities include:
Addressing cavitation, pressure transients, and mechanical wear in public and private water distribution systems.
In high-pressure drop conditions, cavitation can erode valve bodies in months. Our customizable trim configurations divide the pressure drop across multiple stages, preventing vapor pocket collapse and noise.
Featuring hydraulic pilots configured for remote float control, pressure relief, pressure reducing, or solenoid-triggered overrides that work seamlessly with automated SCADA systems.
Internal and external surfaces are coated with Fusion-Bonded Epoxy (FBE) conforming to AWWA C116. Diaphragms are constructed from high-grade EPDM reinforced with nylon fabric, ensuring longevity.
