The manual filter valve adopts the most traditional control method and requires manual operation. There is no raw water bypass during flushing. The handle can be rotated 180° for installation and can be operated under pressure.
The fully automatic filter valve does not need manual operation, which can save part of the manpower. There is a long-term power failure reminder on the control valve, and there is a data protection function after a power failure, which can be maintained for three consecutive days. There is no raw water bypass during flushing, with a signal output port and a remote control port, which can receive passive signals.
Compared with the manual filter valve, the automatic filter valve can set the number of repeated backwashing, that is, run once, backwash and forward wash multiple times. And the fully automatic filter valve has an interlock function, which can be used as a system for simultaneous water supply and separate flushing.
