When a valve slams shut, the moving column of water has to stop somewhere. The resulting pressure spike — water hammer — travels back through the pipework as a shock wave, and over time it loosens joints, cracks fittings and damages pumps. An arrestor gives that energy somewhere to go.
The Niagara range
The range includes the WHA, NHA1, NHA1LF, NHA2LF e NHA3LF models.
Applicazioni
Downstream of quick-closing solenoid and float valves, on appliance branches, in booster set manifolds, and on any line where you can hear a bang when a valve closes.
Selecting an arrestor
Size according to the fixture units served and the pipe run length, and install as close as practical to the source of the surge.
