product description
the static balance valve is a kind of regulating valve with special functions. it has good flow characteristics, can reasonably distribute the flow, realize the quantitative flow, and can effectively solve the problem of uneven room temperature and heat in the heating (air conditioning) system. since the valve is equipped with opening degree indication, opening degree locking device and small pressure measuring valve for flow measurement, it is only necessary to install a balance valve of appropriate size in each branch and user inlet, and use a special intelligent instrument for one-time debugging after locking, the total water volume of the system is controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". this product is ideal in heating systems. the balance valve can be installed on both the water supply pipe and the return pipe. generally, we recommend installing it on the return pipe, especially for high temperature loops. for the convenience of debugging, it should be installed on the return pipe.
