In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The \"butterfly\" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-features-of-china-butterfly-valve-with-handles\">Features of China Butterfly Valve with Handles<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Simple structure and strong universality<\/li>\r\n \t<li>Valve stem with surface hardening treatment<\/li>\r\n \t<li>Adopting a non-pin four-axis connection<\/li>\r\n \t<li>Blow out proof stem<\/li>\r\n \t<li>ISO Top flange<\/li>\r\n \t<li>Isolate the body and stem with medium<\/li>\r\n \t<li>Convenient installation on site<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Applications of China Butterfly Valve with Handles<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list {\"ordered\":true} -->\r\n<ol>\r\n \t<li>Waterworks and water resource project<\/li>\r\n \t<li>Environment Protection<\/li>\r\n \t<li>Public Facilities<\/li>\r\n \t<li>Power and Public Utilities<\/li>\r\n \t<li>Building industry<\/li>\r\n \t<li>Petroleum\/ Chemical<\/li>\r\n \t<li>Steel.

This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug-style valve.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":10,"filter":"raw"},{"term_id":3630,"name":"keystone ball valves","slug":"keystone-ball-valves","term_group":0,"term_taxonomy_id":3630,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3634,"name":"keystone butterfy valve","slug":"keystone-butterfy-valve","term_group":0,"term_taxonomy_id":3634,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3632,"name":"keystone valve company","slug":"keystone-valve-company","term_group":0,"term_taxonomy_id":3632,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3633,"name":"keystone valves suppliers","slug":"keystone-valves-suppliers","term_group":0,"term_taxonomy_id":3633,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3631,"name":"keystone wafer check valve","slug":"keystone-wafer-check-valve","term_group":0,"term_taxonomy_id":3631,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":2546,"name":"Wafer Check Valve","slug":"wafer-check-valve","term_group":0,"term_taxonomy_id":2546,"taxonomy":"post_tag","description":"","parent":0,"count":4,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":2204,"label":"Ball Valves"},{"value":3194,"label":"China Butterfly Valve with Handles Pricelist"},{"value":3630,"label":"keystone ball valves"},{"value":3634,"label":"keystone butterfy valve"},{"value":3632,"label":"keystone valve company"},{"value":3633,"label":"keystone valves suppliers"},{"value":3631,"label":"keystone wafer check valve"},{"value":2546,"label":"Wafer Check Valve"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Keystone Butterfly Valve, Ball Valve, Wafer Check Valve, Keystone Valve Company<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/de\/keystone-butterfly-valve-zeco-valve-company-professional-valve-manufacturer.html\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Keystone Butterfly Valve, Ball Valve, Wafer Check Valve, Keystone Valve Company\" \/>\n<meta property=\"og:description\" content=\"What is Keystone Valve Company?
