Pressure Independent Control Valves By Bray Valves & Controls Pvt. Ltd.

We are well known brand for making and supplying of Pressure Independent Control Valves from Bengaluru, Karnataka, India. The Auto Touch Independent (ATi) valve is a state-of-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 pressure independent control valve that maintains the desired flow rate irrespective of pressure differential changes across the valve within the differential pressure range shown on page AI-8.

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 i? which is most of the time i? differential pressures in the system tend to increase, resulting in overflow through the control valves. This overflow condition results in control instability, and higher pumping costs.
