Sp45f and sp15f digital locking balance valves are regulating valves with special functions of digital locking. They adopt DC valve body structure and have better equal percentage flow characteristics. They can reasonably distribute flow and effectively solve the problem of uneven cooling and heating at room temperature in heating (air conditioning) systems. At the same time, it can accurately adjust the pressure drop and flow to improve the liquid flow state in the pipe network system, so as to achieve the purpose of pipe network liquid balance and source saving.

The valve is equipped with opening indication, opening locking device and small pressure measuring valve for flow measurement. As long as balance valves of appropriate specifications are installed in each branch and user inlet, and locked after one-time commissioning with special intelligent instruments, the total water volume of the system is controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow and small temperature difference". This product is an ideal product in the heating system. It can be installed on both the water supply pipe and the return pipe. Generally, we recommend installing it on the return pipe, especially for the high-temperature loop. For the convenience of debugging, it should be installed on the return pipe. The supply (return) pipe with balance valve does not need to be equipped with stop valve.
