The automatic balancing valve is designed for dynamic maintece of the set differential pressure in sections of two-pipe heating and cooling systems with variable flow rate. During system operation, the pressure difference is transmitted to the diaphragm and compensated by the spring compression force. When the differential pressure starts to change, the core changes its position relative to the body seat under the influence of the diaphragm, thus keeping the set differential pressure constant.
