Product overview
Static balance valve is a kind of regulating valve with special function, has good flow characteristics, can reasonably distribute flow, achieve flow quantity, and can effectively solve the problem of uneven cold and heat at room temperature in heating (air conditioning) system. Since the valve is equipped with an opening indicator, an opening locking device and a pressure measuring small valve for flow measurement, as long as the balance valve of the appropriate specifications is installed in each branch and the user entrance, and the special intelligent instrument is locked after secondary debugging, the total water volume of the system is controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". The product is ideal for heating systems. Balance valve can be installed on the water supply pipe, can also be installed on the return pipe, generally we recommend to install on the return pipe, especially for high temperature loop, in order to facilitate debugging, but also installed on the return pipe.
