Erie Water Treatment Controls introduces its 2401S control valve that allows several valves, hydraulically connected in a parallel configuration, to communicate with each other to avoid simultaneous regeneration. Placing several units in a parallel configuration allows individual flow rates to be added. Each valve individually offers a flow rate of ± 175 ft3/hr (five m³/hr). The modular design offers high redundancy and easy installation, making it possible to add or remove a unit while others remain operational.www.eriewatertreatment.commbuijs@aquion.com
