Knife gate valves are extremely useful when dealing with slurry, abrasive, corrosive, and viscous media. The valves have a low-pressure drop in the fully open position, are simple to operate, light in weight, and cost-effective.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nKnife gate valves are intended to work in the harshest conditions, with a sharpened blade to cut through heavy liquids.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThey are extremely helpful in wastewater applications where corrosion is a major concern. In addition to the valve design that is optimized for slurry media, having a knife gate valve composed of acid-proof stainless steel is advantageous because it is less vulnerable to corrosion damage and therefore requires less frequent maintenance or even replacements.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nKnife gate valves should always be used for applications that require a fully open or completely closed position and should not be used to regulate flow unless specifically designed for it. When fluid is pushed against a partly closed gate, a vibration occurs, gradually eroding the disc and seat. Furthermore, the knife gate valves are intended to open and close slowly to protect against the effects of the water hammer.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:generateblocks\/button-container {\"uniqueId\":\"6d8495a3\",\"isDynamic\":true,\"blockVersion\":2} -->\r\n<!-- wp:generateblocks\/button {\"uniqueId\":\"3d442e11\",\"hasUrl\":true,\"target\":true,\"backgroundColor\":\"#0366d6\",\"textColor\":\"#ffffff\",\"backgroundColorHover\":\"#222222\",\"textColorHover\":\"#ffffff\",\"paddingTop\":\"15\",\"paddingRight\":\"20\",\"paddingBottom\":\"15\",\"paddingLeft\":\"20\"} -->\r\n<a class=\"gb-button gb-button-3d442e11 gb-button-text\" href=\"mailto:commercial@zecovalve.com\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET KNIFE GATE VALVE PRICE<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Specifications of Knife Gate Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Available materials: WCB, WC6, WCC, LCB, LCC, Cast iron, Ductile Iron, SS316, SS304<\/li>\r\n \t<li>Size: 2\u2033 to 80\u2033<\/li>\r\n \t<li>Class: 150 to 300<\/li>\r\n \t<li>Nominal Pressure: PN6 to PN40<\/li>\r\n \t<li>Operation: Handwheel, Electric and Pneumatic Actuated, Gear operated<\/li>\r\n \t<li>Ends: Wafer, Lug, Flanged<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Types of Knife Gate Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Uni-directional Knife Gate Valve<\/li>\r\n \t<li>Bi-directional Knife Gate Valve<\/li>\r\n \t<li>Slurry Knife Gate Valve<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Where is a Knife Gate Valve used?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nKnife gate valves are commonly used in mining, power plants, and the paper, chemical, and food industries. They have the advantage of being very compact due to the linear movement of the shut-off damper (plate that blocks the flow of fluid in the closed position). The knife gate valve is mainly a shut-off valve, although it can be used as a control valve when the shutter is placed in the partially open position.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nKnife gate valves can be used for fluids loaded with solid particles such as wastewater or sludge. As a general rule, the knife gate valve is designed to be sealed on the upstream side of the circuit (on the fluid inlet side), but some valves are sealed on both sides, allowing them to be used regardless of the direction of fluid flow. In the open position, the head loss is very low because the valve does not cause a change in the fluid direction.\r\nThe closing and opening time can be very long, however, and you should consider regular maintenance to correct wear problems between the shutter and sealing elements.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Features of Knife Gate Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Reliability of operation<\/li>\r\n \t<li>The cast body of the valve is dust-tight assuring a clean operation<\/li>\r\n \t<li>Knife action to cut through a standing column of material<\/li>\r\n \t<li>Short opening and closing time<\/li>\r\n \t<li>Maintenance is easy with replaceable packing<\/li>\r\n \t<li>Modular design permitting upgrades to pack and operators<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>World's Largest Gate Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nTexas, the second largest state in the USA both in the area and population faces enormous demand for drinking water.
