Product Detail

Product description

        The static balance valve is a regulating valve with special functions. It has good flow characteristics, can distribute flow reasonably, realize flow quantification, and can effectively solve the problem of uneven heating and cooling at room temperature in the heating (air conditioning) system. Since the valve is equipped with an opening degree indicator, opening degree locking device and a small pressure measuring valve for flow measurement, it is only necessary to install a balance valve of appropriate specifications in each branch and user inlet, and use a special intelligent instrument for second-time debugging After locking, the total water volume of the system is controlled within a reasonable range, thereby overcoming the unreasonable phenomenon of "large flow, small temperature difference". This product is an ideal product in a heating system. The balance valve can be installed on the water supply pipe or on the return pipe. Generally, we recommend to install it on the return pipe, especially for high-temperature loops. To facilitate debugging, it should be installed on the return pipe.
