SP45F-16QDigital Locking Counterbalance ValvesIt is a kind of regulating valve with special function of digital locking, adopting DC-type valve structure, with better equal percentage flow characteristics, which can 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. The valve is equipped with opening degree indication, opening degree locking device and pressure measuring valve for flow measurement, as long as the branch circuit and the user inlet installed with appropriate specifications of thebalancing valveIn addition, with a special intelligent meter for one-time commissioning after locking, the total amount of water in the system is controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". 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, more to be installed in the return pipe, the installation of the balance valve for the supply (return) pipe do not have to set up again!stop valveThe
