Self-balancing valve can be in the absence of an external power supply, the system automatically balances traffic. Self-balancing valve is to maintain the orifice (fixed aperture) before and after the differential pressure to achieve a limited flow, therefore, can also be called the flow valve. Fixed flow valve is the role of object flow, to lock the flow of water through the valve, rather than against the balance of resistance. He can solve the system's dynamic imbalance: In order to maintain the efficient operation of a single chiller, boiler, cooling tower, heat exchanger these devices need to control the flow of these devices is fixed at the rated value; From the end of the system, in order to avoid Dynamic adjustment of the interaction, but also need to end the flow of devices or branches. In the design should be noted that the drawback of self-operated flow control valve is that the valve has the minimum requirements of poor work, the general requirements of the product minimum working pressure 20KPa, if installed in the most adverse circuit, will inevitably require more circulating water pump 2 m water column Working lift, it should be taken near-end installation, distal uneasy approach. Do not install this self-operated flow control valve when the user is at a distance greater than 80% of the heating radius from the heat source.
