The Auto Touch Independent Max (ATiMX) valve brings pressure independent control technology to valves up to 6" and flow rates up to 468 GPM. It is a stateof-the-art control valve combining a high quality/high rangeability temperature control valve with a dynamically balanced flow regulator in the same space-saving housing. The result is a pressureindependent control valve that maintains the desired flow rate irrespective of the pressure differential across the valve.
Even the most controllable standard (pressure dependent) temperature control valve will allow a change in flow as the differential pressure in the system changes, which is an everyday occurrence. Any time a chilled water or hot water system is operating at less than design maximum load conditions – which is most of the time – differential pressures in the system tend to increase, resulting in overflow through the controlvalves. This overflow condition results in control instability, and higher pumping costs.
Balancing valves, either manual or automatic, can only prevent overflow at conditions above design maximum flow. At any flow condition less than design maximum, balancing valves do not fulfill any purpose. The ATiMX valve provides a cost effective means of controlling hot water and chilled water flow in an accurate and stable manner while minimizing pumping, heating and cooling costs. And by combining the automatic temperature control function and the dynamic balancing function in a single device, installation costs are also reduced.
