A.R.I. USA Inc.

A.R.I. USA, a division of the Aquestia Group, is a manufacturer of air valves and hydraulic control valves for water, wastewater, and industrial pipeline systems. The company traces its heritage to DOROT's 80-plus years of hydraulic valve expertise and now operates under three unified brands — A.R.I., DOROT, and OCV — serving over 140 countries through 12 subsidiary offices. A.R.I. developed the world's first composite-material air valves for wastewater and a conical-shaped air valve design that reserves air pocket formation. Their air valve portfolio includes combination air valves (D-040 Barak, D-070 dynamic rolling-diaphragm), air and vacuum valves (K-060 HF, K-020/K-022 series), automatic air release valves (S-015, S-050 Segev, S-020 series), vacuum breaker valves (VB-060), and underground air valve vault systems for both water and wastewater mains. DOROT hydraulic control valves cover pressure reducing (S300 PRM), pressure sustaining, level control, pressure relief, and quick-release applications. OCV contributes the S100 68F Series with FM Approval for fire protection. Products carry NSF/ANSI/CAN 61 and 372 lead-free certifications, ATEX explosion-proof ratings for hazardous wastewater environments, and EN 1074-1/4 compliance. The company also offers ARIavCAD cloud-based air valve sizing and placement software, ARISENSE smart monitoring for waterworks and wastewater networks, CONDOR monitoring, and BIM models for Revit integration.
