con lati paralleli tra loro che scorre adesa a due seggi.<\/span><\/p><p><span style=\"font-weight: 400;\">Le valvole a saracinesca sono spesso collocate sulle teste di pozzo dei <\/span><b>giacimenti petroliferi<\/b><span style=\"font-weight: 400;\"> e vengono utilizzate per controllare il flusso estratto dalla falda stessa. In questi ambiti ci si trova spesso in presenza di liquidi o gas inquinati da <\/span><b>particelle abrasive e corrosive<\/b><span style=\"font-weight: 400;\">. Proprio per questi motivi l\u2019otturatore e i seggi vanno nobilitati con <\/span><b>trattamenti<\/b><span style=\"font-weight: 400;\"> che ne aumentino la vita utile in esercizio e ne <\/span><b>garantiscano il corretto funzionamento <\/b><span style=\"font-weight: 400;\">anche dopo anni di installazione.

Il carburo di tungsteno legato al cobalto e miscelato ad una piccola quantit\u00e0 di cromo \u00e8 sicuramente una delle polveri pi\u00f9 richieste per questa specifica applicazione. La matrice in cromo migliora la resistenza alla corrosione mentre i fini grani di carburo legati dal cobalto, garantiscono una indiscussa resistenza ad erosione ed abrasione da sfregamento.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c99b47e elementor-widget elementor-widget-raven-image\" data-id=\"c99b47e\" data-element_type=\"widget\" data-widget_type=\"raven-image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"raven-image\">\n\t\t\n\t\t\n\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/www.metalvarnew.com\/wp-content\/uploads\/2022\/02\/valvole-a-saracinesca-1.jpg\" class=\"attachment-full size-full wp-image-5722\" alt=\"\" srcset=\"https:\/\/www.metalvarnew.com\/wp-content\/uploads\/2022\/02\/valvole-a-saracinesca-1.jpg 1920w, https:\/\/www.metalvarnew.com\/wp-content\/uploads\/2022\/02\/valvole-a-saracinesca-1-300x169.jpg 300w, https:\/\/www.metalvarnew.com\/wp-content\/uploads\/2022\/02\/valvole-a-saracinesca-1-1024x576.jpg 1024w, https:\/\/www.metalvarnew.com\/wp-content\/uploads\/2022\/02\/valvole-a-saracinesca-1-768x432.jpg 768w, https:\/\/www.metalvarnew.com\/wp-content\/uploads\/2022\/02\/valvole-a-saracinesca-1-1536x864.jpg 1536w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5093e91 elementor-widget elementor-widget-text-editor\" data-id=\"5093e91\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h2><span style=\"font-weight: 400;\">Coating HVOF per valvole a saracinesca<\/span><\/h2><p>\u00a0<\/p><p><span style=\"font-weight: 400;\">Per applicare le polveri sulle valvole a saracinesca, la tecnologia utilizzata \u00e8 quella <\/span><b>HVOF. <\/b><span style=\"font-weight: 400;\">l grado di finitura che una valvola gate richiede, infatti, necessita di un riporto il pi\u00f9 compatto e adesso possibile.
