Descrizione del prodotto<\/h2>\n

Unlike ball valves which close in a quarter-turn, the Valvola a saracinesca<\/b> operates by lifting a rectangular gate out of the path of the fluid via a multi-turn handwheel. When fully open, the gate completely clears the passage, leaving no obstruction to flow.<\/p>\n

Caratteristiche tecniche principali:<\/b><\/h2>\n
    \n
  • Modello:<\/b> GT<\/li>\n
  • Materiale del corpo:<\/b> Acciaio inossidabile ASTM 316<\/li>\n
  • Pressione nominale:<\/b> 200 WOG<\/li>\n
  • Gamma di dimensioni:<\/b> 1\/2″ ~ 2″<\/li>\n
  • Operazione:<\/b> Handwheel (Multi-turn)<\/li>\n<\/ul>\n

    This design is particularly useful in applications where “Water Hammer” (shock waves caused by sudden valve closure) is a concern, as the slow-closing mechanism naturally dampens pressure spikes.<\/p>\n

    Vantaggi e benefici<\/h2>\n
      \n
    • Prevents Water Hammer:<\/b> The multi-turn operation ensures gradual flow reduction, protecting pipes and pumps from hydraulic shock.<\/li>\n
    • Minimal Pressure Drop:<\/b> When fully open, the valve allows straight-through flow with almost zero resistance.<\/li>\n
    • Precise Control:<\/b> While primarily an isolation valve, the threaded stem allows for finer adjustment of flow compared to a ball valve.<\/li>\n
    • Compact Face-to-Face:<\/b> Generally narrower than globe valves, fitting into tighter linear spaces.<\/li>\n<\/ul>\n

      Campi di applicazione e ubicazioni<\/h2>\n
        \n
      • General Plumbing:<\/b> Main water shut-off valves for buildings.<\/li>\n
      • Viscous Fluids:<\/b> Suitable for heavier oils where flow resistance must be minimized.<\/li>\n
      • Steam Supply (Low Pressure):<\/b> Basic steam isolation.<\/li>\n
      • Irrigation Systems:<\/b> Preventing pipe damage from pressure surges.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"

        Precise Flow Regulation for Low-Pressure Systems.<\/b><\/p>\n

        Il GT Series Manual Threaded Gate Valve<\/b> is a classic solution for on\/off control where full flow with minimal pressure drop is required. Constructed from Acciaio inossidabile 316<\/b> and rated for 200 WOG<\/b>, this valve is designed for systems where the prevention of water hammer is prioritized over rapid shut-off.<\/p>","protected":false},"featured_media":3763,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[58],"product_tag":[],"class_list":{"0":"post-3823","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-manual-ball-valve","7":"desktop-align-left","8":"tablet-align-left","9":"mobile-align-left","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/product\/3823","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/media\/3763"}],"wp:attachment":[{"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/media?parent=3823"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/product_brand?post=3823"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/product_cat?post=3823"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ballvalves.tw\/it\/wp-json\/wp\/v2\/product_tag?post=3823"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
