ATi MAX GENERAL DESCRIPTION ATi Max Series Valves are self-balancing, dynamic flow control valves that are pressure-independent, two-way, modulating to accept digital or analog input signals. The valves accept 0-10V DC, 2-10V DC, 0-20mA, 4-20mA or 2-position / 3-point floating input signals. Each valve has an adjustable maximum flow rate setting to enable flow limitation and balancing to the coils or zones that the valves are controlling. All ATi Max actuators are microprocessor-based with a self-calibrating feature.
