Valmet IQ Steam Profiler

IQ Steam Profiler is a multi-zone steam actuator system that provides unique profiling accuracy through its electromechanical actuator with position feedback. It features advanced steam injection technology that maximizes steam absorption efficiency and temperature increase, providing very high dryness after the press.
