Refer to the standard piping diagram when installing the valve.
Install the valve near to the manhole for easy maintenance.
Prior to installing the valve, flush the pipe line to clean inside.
It is recommended to install an alarm system in the monitoring room to detect an unexpected overflow caused by any other reason except our valve.
To prevent waves while filling the water tank, a flow induction pipe with syphon braking hole should be installed.
The valve should be installed vertically on the main pipe line, and the length of flow induction pipe should be longer than H3 suggested in the above table.
