{"id":572,"count":5,"description":"When a valve slams shut, the moving column of water has to stop somewhere. The resulting pressure spike &mdash; water hammer &mdash; 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.\n\n<strong>The Niagara range<\/strong>\n\nThe range includes the <strong>WHA<\/strong>, <strong>NHA1<\/strong>, <strong>NHA1LF<\/strong>, <strong>NHA2LF<\/strong> e <strong>NHA3LF<\/strong> models.\n\n<strong>Applicazioni<\/strong>\n\nDownstream 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.\n\n<strong>Selecting an arrestor<\/strong>\n\nSize according to the fixture units served and the pipe run length, and install as close as practical to the source of the surge.","link":"https:\/\/niagarapumps.ca\/it\/product-category\/valves\/water-hammer-arrestor\/","name":"SCARICATORE DI COLPI D'ARIETE","slug":"dispositivo-anticollasso-idraulico","taxonomy":"product_cat","parent":115,"meta":[],"menu_order":0,"_links":{"self":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/product_cat\/572","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/product_cat\/115"}],"wp:post_type":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/product?product_cat=572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
