Self-operated pressure control valve Overview:

ZYC-type self-operated pressure control valve is a kind of energy-saving products that use self-control of pressure changes of medium to keep the pressure difference flowing through the controlled system medium unchanged. It is suitable for the heating mode to adopt the pressure control of double pipe system to ensure the pressure drop of the system is basically the same, reduce the noise, balance the resistance and eliminate the hydraulic imbalance of the heating network.
