SP45F-16Q Digital Locking Balance Valve is a kind of regulating valve with special function of digital locking, adopting DC-type valve body structure, with better equal percentage flow characteristics, able to reasonably distribute the flow and effectively solve the problem of uneven room temperature in heating (air conditioning) system. At the same time, it can accurately adjust the pressure drop and flow rate, which is used to improve the liquid flow state in the pipeline network system, and achieve the purpose of pipeline network liquid balance and source saving. Valve is equipped with opening degree indication, opening degree locking device and pressure measuring valve for flow measurement, as long as the appropriate specifications of the balance valve installed in each branch and the user's entrance, and a special intelligent instrument for one-time debugging after locking, the total amount of water to control the system in a reasonable range, thus overcoming the “large flow, small temperature difference” of irrationality. Phenomenon. This product is the ideal product in the heating system. Both can be installed in the water supply pipe, can also be installed in the return pipe, generally we recommend installing in the return pipe, especially for high temperature loop, in order to facilitate debugging, but also to be installed in the return pipe, the installation of the balancing valve for the supply (return) pipe do not have to set up a shut-off valve.
