It is designed for fluids containing suspended solids: slurries, cellulose pulps, mineral concentrates, loaded water. DN 32 to 1400, up to 10 bar.  <\/p>\n<h2>How does the unidirectional knife gate valve work?<\/h2>\n<p>The blade slides vertically in internal guides machined into the body. In the closed position, it presses against the downstream seat. Sealing works in one direction only: upstream pressure keeps the blade in contact with its seat. The directional arrow engraved on the body indicates the correct installation orientation.<br \/>This is where &#8220;unidirectional&#8221; makes sense. No bonnet, no external mechanical seal: the construction is simpler and maintenance less demanding than a bidirectional gate valve. For the vast majority of loaded fluid applications where flow direction is fixed, this is sufficient. When pressure can reverse or exceeds 10 bar, the KGVB bonnet knife gate valve is the right choice.      <\/p>\n<p style=\"text-align: center;\"><a class=\"btn-configurateur elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/flowrates-valves.com\/summary\/reciIAh8qOpRU6Hkf\" target=\"_blank\" rel=\"noopener\"><span class=\"elementor-button-content-wrapper\"><span class=\"elementor-button-text\">Configure your valve here<\/span><\/span><\/a><\/p>\n","protected":false},"featured_media":909,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[35],"product_tag":[],"class_list":["post-1039","product","type-product","status-publish","has-post-thumbnail","product_cat-energy","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product\/1039","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/comments?post=1039"}],"version-history":[{"count":6,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product\/1039\/revisions"}],"predecessor-version":[{"id":1812,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product\/1039\/revisions\/1812"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/media\/909"}],"wp:attachment":[{"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/media?parent=1039"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product_brand?post=1039"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product_cat?post=1039"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/flowrates.com\/en\/wp-json\/wp\/v2\/product_tag?post=1039"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
