Válvulas de Retención tipo Mariposa de Spears®
Características Principales:
—> Fabricadas en PVC y CPVC con empaques EPDM o FKM.
—> Las Válvulas de Retención tipo Mariposa de Spears® ofrecen una respuesta muy rápida al contraflujo sin golpeteo.
—> Dado que casi todos los componentes son internos no requieren más espacio que un tramo de tubería y una conexión.
—> Su diseño incorpora un sello elastomérico reforzado y flexible para una larga vida útil y es adecuado para montaje en cualquier posición (horizontal, vertical, ascendente o descendente), lo que le brinda una mayor versatilidad.
—> Disponibles en tamaños IPS de 2 a 12” con conexiones de extremo bridadas, espiga, rosca macho, ranuradas y wafer.
—> Pueden utilizarse como válvulas de pie de cisterna (foot valve).
—> En tamaños IPS de 14″ a 24″ con conexiones bridadas, espiga, ranuradas y wafer.
—> Clasificación de presión de 150 psi para agua a 73°F para tamaños de 2″ a 8″, de 100 psi para tamaños de 10″ a 16″ y de 50 psi para tamaños de 18″ a 24″.
—> Las válvulas bridadas están diseñadas para montarse entre dos (2) bridas con patrón de pernos ANSI Clase 125/150, utilizando juntas de cara completa de 1/8″
—> Los extremos con rosca macho son de rosca NPT estándar.
—> Los extremos ranurados son para uso con acoplamientos mecánicos diseñados para tuberías termoplásticas.
Especificación de Ingeniería:
Todas las Válvulas de Retención termoplásticas son de diseño tipo Mariposa construidas en PVC de Clasificación de Celda 12454 o CPVC de Clasificación de Celda 23447. Las válvulastienen extremos bridados, de espiga, roscados macho, ranurados o tipo wafer. Todos los sellos de válvula son de EPDM reforzado o FKM con un ensamblaje interno reemplazable en campo. Todas las válvulas de 2″ a 8″ tienen una clasificación de presión de 150 psi, todas las de 10″ a 16″ a 100 psi y todas las de 18″ a 24″ a 50 psi para agua a 73°F, tal como son fabricadas por Spears® Manufacturing Company.
