Ductile iron balance valve is a manual preset valve,
which can adjust the flow rate and balance function. It has better
equal percentage flow characteristics, can distribute flow
reasonably, and effectively solve the problem of heating (air
conditioning) system. The problem of uneven heat and temperature at
room temperature. At the same time, the pressure drop and flow rate
can be accurately adjusted, which can improve the liquid flow state
in the pipe network system, achieve the liquid balance of the pipe
network and save energy. At the same time, by installing the
balancing valve, the total water volume of the system can be
controlled within a reasonable
