IMI CCI Valve Alternative
IMI Critical Engineering / IMI CCI Control Valves
IMI CCI (part of IMI Critical Engineering, a division of IMI plc) pioneered the DRAG® multi-stage tortuous-path trim technology — the industry benchmark for eliminating cavitation, flashing, and high-velocity erosion in critical flow control applications. IMI CCI valves are the reference product at NTPC, Adani Power, and Tata Power supercritical power plants for feedwater heater drain, main steam letdown, and boiler startup bypass service. In the oil & gas sector they are specified for high-pressure gas letdown and choke duty. Vajra supplies severe-service globe control valves with engineered anti-cavitation trim for comparable applications at a fraction of the imported cost.
