Engineered Case Studies & Technical Reports
Documented performance records showing measurable reductions in head-loss energy consumption and downtime prevention.
Metropolitan Water Reclamation District: 450 MGD Filter Gallery Modernization
Replaced 128 leaking metal-seated gate valves with custom vulcanized-seat VALVEX RSV-150W butterfly units. The retrofit eliminated transient water hammer chatter during automated filter backwashes and dropped pumping energy consumption by 14.2% across four distribution quadrants.
Regional Biosolids Pipeline: Mitigating 18% Dry Solids Slurry Abrasion
Conventional ductile knife gates experienced severe packing blowout and seat scoring every 4 months due to silica sand entrainment. VALVEX installed KGV-400 valves equipped with ceramic-infused polyurethane sleeve seats, successfully exceeding 5 years of continuous MTBF under 12 Bar pulsing feed.
Desalination Intake Facility: Super Duplex 2507 Assemblies for 42,000 ppm Chlorides
Deep intake headers required immunity to high-temperature hyper-saline crevice attack. VALVEX engineered triple-offset disc closures utilizing Super Duplex UNS S32750 metallurgy with Stellite Grade 21 hardfacing, with zero pitting corrosion detected over 48,000 operational duty hours.
Stamped Water Sector Compliance Matrix
Every VALVEX water component is serialized, factory hydrostatic test-stamped to ISO 5208, and accompanied by EN 10204 3.1 material test certificates.
