Browse our range to find the perfect disc shutter for any of your project needs.\r\n<h2>UKSPAR disc valve: an effective solution for industrial and municipal systems<\/h2>\r\nButterfly valves (rotary valves) are modern shut-off and control devices used to shut off or regulate the flow in pipelines. UKSPAR brand products, presented on the UKSPAR website, combine reliable design, high tightness and ease of operation. Butterfly valves are used in systems with working media: water, air, slightly aggressive media, gas, petroleum products.\r\n<h2>Purpose and application of rotary disc dampers<\/h2>\r\nThe rotary disc valve performs the function of closing, opening and regulating the flow of the medium in the pipeline. Areas of application:\r\n<ul>\r\n \t<li>water and sewage networks;<\/li>\r\n \t<li>heating and ventilation systems;<\/li>\r\n \t<li>chemical and food industry;<\/li>\r\n \t<li>energy and agro-industrial enterprises;<\/li>\r\n \t<li>industrial pumping units;<\/li>\r\n \t<li>utility companies.<\/li>\r\n \t<li>oil and gas companies<\/li>\r\n<\/ul>\r\nDue to its ease of installation, the interflange disc gate valve is actively used for the modernization of old and construction of new pipeline networks, as it is installed without the need to change the length of the pipeline, is compatible with standard flanges, and does not require complex tools for maintenance.\r\n<h2>The principle of operation of a butterfly valve<\/h2>\r\nA rotary valve consists of a body, a disc, a shaft, a seal, and sealing elements.\r\n<ul>\r\n \t<li>in the open state - parallel to the flow, passes liquid or air;<\/li>\r\n \t<li>in closed position - blocks the flow, creating a hermetic seal.<\/li>\r\n<\/ul>\r\nWorkflow:\r\n<ol>\r\n \t<li>The operator turns the handle or activates the electric or pneumatic actuator, depending on the technical solution.<\/li>\r\n \t<li>The disc blocks or opens the flow in the pipeline by 90\u00b0.<\/li>\r\n<\/ol>\r\nDue to the minimal number of moving parts, such a mechanism is reliable, wear-resistant and does not require complex maintenance.\r\n<h2>Types of disc valve connections<\/h2>\r\nThe Uxpar website presents <a href=\"https:\/\/ukspar.ua\/en\/zatvory-mezhflancevi\/\">interflange disc valves<\/a>, installed between two pipeline flanges. This is the most common type of installation due to the following advantages:\r\n<ul>\r\n \t<li>does not require a large installation length;<\/li>\r\n \t<li>convenient for replacement without dismantling the entire assembly;<\/li>\r\n \t<li>suitable for DN from 40 to 600 mm (according to the size table on the Uxpar website).<\/li>\r\n<\/ul>\r\nIn addition to interflange models, the UKSPAR range also includes:\r\n<ul>\r\n \t<li><a href=\"https:\/\/ukspar.ua\/en\/zatvory-pryvarni\/\">Welded disc valves<\/a> \u2014 are mounted by welding, which guarantees tightness even in systems with high pressure or vibration. They are used in technological lines where maximum connection reliability is important.<\/li>\r\n \t<li><a href=\"https:\/\/ukspar.ua\/en\/zatvory-flancevi\/\">Flanged valves<\/a> \u2014 equipped with their own flanges for connection to other system components. This is the optimal solution for large diameter pipelines or for facilities with regular maintenance.<\/li>\r\n<\/ul>\r\nThere are also versions with a worm gear for easier control of large diameters or in places with difficult access.\r\n<h2>UKSPAR disc gate materials: exact match to the environment<\/h2>\r\nThe UKSPAR line includes disc valves with a wide variety of body, disc and seal materials, which allows you to choose a solution for any environment: drinking water, technical liquids, gas, oil products, air and mildly aggressive environments. Types of bodies:\r\n<ul>\r\n \t<li>Ductile iron GGG40 \/ GGG50 is a classic choice for water, heating, air (Fig. P201, P202, P203, P204, P226, P101);<\/li>\r\n \t<li>Stainless steel - for chemical and food environments where complete corrosion resistance is required (Fig. P203, P221);<\/li>\r\n \t<li>Bronze C95400 - increased resistance to salts. Used for seawater desalination systems (Fig. P228);<\/li>\r\n<\/ul>\r\nTypes of discs:\r\n<ul>\r\n \t<li>Cast iron GGG40 \/ GGG50 - base disc with protective coating (Fig. P201);<\/li>\r\n \t<li>Stainless steel AISI 304 \/ 316 - resistant to corrosion, high temperatures, acids and alkalis (Fig. P202, P203, P204, P221);<\/li>\r\n \t<li>PTFE (Teflon) coated steel \u2014 chemical inertness and smoothness (Fig. P221, P226);<\/li>\r\n \t<li>Bronze C95400 \u2014 for seawater desalination (Fig. P228).<\/li>\r\n<\/ul>\r\nTypes of seals:\r\n<ul>\r\n \t<li>EPDM - universal for drinking water, air, sewage networks (Fig. P201, P202, P228, P101);<\/li>\r\n \t<li>NBR \u2014 resistance to oils, fuels and lubricants, moderately aggressive environments (Fig. P204);<\/li>\r\n \t<li>PTFE (Teflon) \u2014 the highest resistance to chemicals and temperatures (fig. P203, P221, P226).<\/li>\r\n<\/ul>\r\n<h2>Structural types of UKSPAR valves<\/h2>\r\nThe product range covers all main types of shut-off valves by installation method.\r\n<h3>Interflange butterfly valves<\/h3>\r\nThe most compact, installed between the flanges of the pipeline (in the open position).
