Engineered for industrial pipelines, this valve delivers precise ON\/OFF and modulating control while maintaining zero leakage even under high pressure and temperature conditions. Its flanged design allows for secure installation in pipelines ranging from DN50 to DN2000. Constructed from durable cast steel, stainless steel, or special alloy materials, with PTFE or flexible graphite seats, the valve ensures long-term reliability and resistance to wear and corrosion. Optional accessories, including limit switches and electric\/pneumatic positioners, enable remote monitoring and automated flow control for demanding industrial applications.<\/p>","protected":false},"featured_media":9577,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[41],"product_tag":[95],"class_list":{"0":"post-9571","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-pneumatic-actuator-butterfly-valve","7":"product_tag-aw-series","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/product\/9571","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/media\/9577"}],"wp:attachment":[{"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/media?parent=9571"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/product_brand?post=9571"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/product_cat?post=9571"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.fleyendavalve.com\/fr\/wp-json\/wp\/v2\/product_tag?post=9571"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
