SP45F,SP15F Digital Lock Balance ValveDetailed product description：

SP45F and SP15F digital locking balance valves are regulating valves with special digital locking functions. They adopt a DC valve body structure and have better equal percentage flow characteristics, which can reasonably distribute flow and effectively solve the problem of uneven temperature distribution in heating (air conditioning) systems. At the same time, it can accurately adjust pressure drop and flow rate to improve the liquid flow state in the pipeline system, achieve liquid balance in the pipeline system, and save resources. The digital locking balance valve is equipped with an opening indicator, an opening locking device, and a pressure measuring small valve for flow measurement. As long as appropriate specifications of balance valves are installed in each branch and user inlet, and a dedicated intelligent instrument is used for one-time debugging and locking, the total water volume of the system can be controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". The digital locking balance valve is an ideal product in the heating system. It can be installed on both the supply pipe and the return pipe. Generally, we recommend installing it on the return pipe, especially for high-temperature circuits. To facilitate debugging, it should be installed on the return pipe. The supply (return) pipe with a balance valve does not need to be equipped with a shut-off valve.
