The SP45F digit locking balance valve is a regulating valve with digit locking function. It adopts a DC valve body structure and has good equal percentage flow characteristics, which can distribute flow and solve the problem of uneven temperature in heating (air conditioning) systems. At the same time, it can accurately adjust the pressure drop and flow rate to improve the liquid flow state in the pipeline network system, achieve the goal of liquid balance in the pipeline network and save sources. The valve is equipped with an opening indicator, an opening locking device, and a pressure measuring small valve for flow measurement. As long as appropriate balance valves are installed in each branch and user inlet, and intelligent instruments are used for one-time debugging and locking, the total water volume of the system is controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". This product is an ideal product in heating systems. It can be installed on both the water supply pipe and the return pipe. Generally, we recommend installing it on the return pipe. For high-temperature loops, for easy debugging, it should be installed on the return pipe. Supply (return) pipes with balance valves generally do not need to be equipped with shut-off valves.
This valve is mainly used in boilers or chillers, residential heating and air conditioning systems, heating stations, etc.
Product structure features:
- Ideal regulation performance;
- Better cut-off function;
- Display the opening status accurate to 1/10 turn;
- The theoretical flow characteristic curve is an equal percentage characteristic curve;
- The theoretical characteristic curve is an equal percentage curve, and the actual curve is linear when the valve weight is between 0.3 and 0.5;
There is a fixed flow coefficient for each entire cycle, and during debugging, as long as the pressure difference at both ends of the valve is measured, the flow rate through the valve can be easily calculated.
