Installation of the injector on a bypass line
It is necessary to fit the proportional dosing injector on a bypass line when irrigating with a flow
rate higher than 25 m
3
/hour. The bypass enables only part of the water flow to pass to the
Injector and activate it, while the rest passes through the main line. Using the choke valve on
the main line, the flow of water passing through the main line is regulated so that only
A proportion of the flow passes through the bypass and activates the injector. The metering must
be calculated in accordance with the flow rate passing through both lines.
It is necessary to fit a main valve at the beginning of the line (1), water filter of 200 mesh (2),
backflow prevention valve (3) must be fitted to a drinking water line, according to local
regulations, in order to prevent entry of chemicals to the drinking water. A pressure reducer (4),
a T connection for diversion from the main line to the bypass, a valve(5)on the bypass before the
inlet to the proportioning dosing injector, a valve (6) after the outlet from the injector on the
bypass, and a T connector for the return to the main line. On the main line between the bypass
junction and the return connection a choke valve should be fitted (7), preferably an angled valve,
to regulate the flow rates between the main line and the bypass.
After the return connection from the bypass there should be fitted anti vacuum valve (8) and
valves for the branch lines (9).
