Las válvulas globo Serie 84 son válvulas de movimiento lineal diseñadas para detener el flujo del fluido cuando sea necesario. Tienen cuerpo con tapa atornillada, husillo y yugo externos, volante de mano ascendente, y el elemento de cierre es un disco que se asienta contra un asiento mecanizado, logrando un cierre seguro. El sellado con la atmósfera se consigue mediante anillos de grafito flexible. El flujo es ascendente bajo el asiento, siendo válvulas unidireccionales. Su cuerpo tipo weir genera mayor pérdida de presión que las válvulas de compuerta, pero permite una operación más rápida y regulación cuando se usan con tapón de estrangulamiento. Son fáciles y seguras de operar, ampliamente utilizadas en industrias eléctrica, química y petrolera. Se accionan manualmente o con engranaje según tamaño y presión, y pueden adaptarse a automatización con distintos actuadores.
