Uma v\u00e1lvula de reten\u00e7\u00e3o wafer tamb\u00e9m \u00e9 chamada de v\u00e1lvula de contracorrente, v\u00e1lvula de reten\u00e7\u00e3o, v\u00e1lvula de contrapress\u00e3o e v\u00e1lvula unidirecional. Este tipo de v\u00e1lvula \u00e9 aberta e fechada automaticamente pela for\u00e7a gerada pelo fluxo do pr\u00f3prio meio na tubula\u00e7\u00e3o e pertence a uma v\u00e1lvula autom\u00e1tica. V\u00e1lvulas de reten\u00e7\u00e3o s\u00e3o usadas em sistemas de dutos. Suas principais fun\u00e7\u00f5es s\u00e3o evitar o refluxo do meio, reverter as bombas e seus motores de acionamento e liberar o meio em cont\u00eaineres. As v\u00e1lvulas de reten\u00e7\u00e3o tamb\u00e9m podem ser usadas em tubula\u00e7\u00f5es para alimentar sistemas auxiliares onde a press\u00e3o pode subir mais do que a press\u00e3o do sistema principal. As v\u00e1lvulas de reten\u00e7\u00e3o podem ser usadas em tubula\u00e7\u00f5es de v\u00e1rios meios de acordo com diferentes materiais.

When the flow decreases, the plates close by torsion spring action without requiring reverse flow.\r\n\r\n\r\n\r\n\r\n\r\nThis design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together to make the Dual Plate Check Valve NRV one of the most efficient designs.\r\n\r\n\r\n\r\n\r\n\r\nDuo Disc Check Valves are available in wafer design, flanged wafer design, and extended design with flanged ends having face to face dimensions as that of a swing check valve. It is also referred to as SILENT CHECK VALVE.\r\n\r\n\r\n\r\n\r\n

Standard vs. Retainerless Body Designs<\/h2>\r\n\r\n\r\n\r\n\r\nAs a leading API 594 dual plate check valve manufacturer, our Dual Plate Wafer Check Valves are available in two different body styles\u2014Standard and Retainerless. Both versions have the same performance, dimensions, and ratings. In all dual plate check valves, the center pin (off which the discs rotate) and the limiter bar (which prevents the discs from hitting each other) need to be affixed to the valve body. In a standard body style, the result is penetration through the body wall. In a retainerless design, a sleeve is inserted into the inside of the body, thus avoiding penetrating the body wall. This makes retainerless style valves particularly desirable and applicable for critical Hydrocarbon and Chemical processing applications, or any service where environmental safety or fire hazards are concerned.\r\n\r\n","parent":0,"count":2,"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":2343,"label":"check valve"},{"value":2848,"label":"Dual Plate Wafer Check Valve Supplier"},{"value":2546,"label":"Wafer Check Valve"}]},"yoast_head":"\n
