Hydraulic normally open electric check valve SV12-21

The balance valve is an adjustable valve with special function of digital locking. It adopts direct-flow valve body structure, has better equal percentage flow characteristics, can distribute the flow reasonably, and effectively solves the problem of uneven room temperature in heating (air conditioning) system. At the same time, the pressure drop and flow rate can be accurately adjusted to improve the liquid flow state in the pipe network system and achieve the purpose of liquid balance and energy saving in the pipe network. The valve is equipped with opening indicator, opening locking device and small pressure measuring valve for flow measurement. As long as the balance valves with appropriate specifications are installed in each branch and user entrance and locked after one-time debugging 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". The balance valve can be installed on both water supply pipe and return pipe, generally on return pipe. Especially for the high temperature loop, it should be installed on return pipe for convenience of debugging, and the water supply (return) pipe with the balance valve does not need to be equipped with a stop valve. Install a balance valve in the pipeline system, and adjust it to change the ratio of characteristic resistance of the pipeline system, so as to meet the design requirements. After the system debugging is qualified, there is no static hydraulic imbalance problem. If the qualified system is in partial load operation, when the total flow decreases, the flow of each branch pipe regulated by the balance valve will automatically decrease year-on-year, but the flow ratio set by each branch pipe remains unchanged.
