Self-operated differential pressure control valve
Self-operated differential pressure control valve
ZYC self-operated differential pressure control valve is an energy-saving product that uses the pressure change of the medium to control itself and keep the pressure difference of the medium flowing through the controlled system unchanged.
Self-operated differential pressure control valve overview:
ZYC self-operated differential pressure control valve is an energy-saving product that uses the pressure change of the medium to control itself and keep the pressure difference of the medium flowing through the controlled system unchanged. It is suitable for the heating mode to adopt the differential pressure control of the double pipe system to ensure that the pressure difference of the system is basically unchanged, reduce the noise, balance the resistance, and eliminate the hydraulic imbalance of the heating network.
