Manual filter valve adopts the most traditional control mode, which needs manual operation. There is no by-pass of raw water during flushing, and the handle can be rotated by 180, which can be operated with pressure.
Automatic filter valve does not need manual operation, which can save some manpower. There is a long-term power failure prompt on the control valve, and there is a data protection function after power failure, which can last for three consecutive days. There is no raw water bypass during flushing, with signal output port and remote control port, which can receive passive signals.
Compared with the manual filter valve, the automatic filter valve can set the number of times of repeated backwashing, that is, running once, backwashing and forward washing many times. And the full-automatic filter valve has interlocking function, which can be used as a system for supplying water and washing separately at the same time.
