Product features:

ZL47F-16 self operated balance valve is mainly composed of an automatic regulating valve disc and a manual regulating valve disc. Using the pressure change of the medium as the power, it can automatically adjust the balance of the flow of each branch pipe and accurately stabilize the flow. At the same time, it has the functions of opening indication, locking and closing. It is suitable for flow control of non corrosive media such as heating and air conditioning. One time adjustment before operation can make the system flow automatically constant at the required set value.
