What were the main challenges that you faced before partnering with Dynamic Fluid Control, and how were they addressed?
Before partnering with Dynamic Fluid Control, we encountered challenges related to air accumulation in pipelines – leading to inefficiencies, pressure fluctuations, and increased strain on critical infrastructure. Traditional air valves required frequent maintenance and were prone to premature failure, causing operational disruptions. The RGXII Air Valves addressed these issues through incorporating a self-cleaning mechanism, corrosion-resistant materials, and superior sealing capabilities. These enhancements have significantly reduced maintenance interventions, ensuring a more reliable and high-performing water and wastewater system that consistently serves our customers and stakeholders.Can you describe the impact of the RGXII air valves on pipeline reliability and maintenance schedules?
