Abstract

Un ensamblaje de reguladores de doble puerto incluye un primer puerto de líquido y un segundo puerto de líquido. Se coloca un ensamblaje de asiento de válvula fijo próximo al primer puerto de líquido y se coloca un ensamblaje de asiento de válvula flotante próximo al segundo puerto de líquido. Un primer obturador de válvula coopera con el ensamblaje de asiento de válvula fijo para abrir y cerrar el primer puerto de líquido y un segundo puerto de líquido coopera con el ensamblaje de asiento de válvula flotante para abrir y cerrar el segundo puerto de líquido. El ensamblaje de asiento de válvula flotante incluye un asiento de válvula flotante que puede moverse con respecto al asiento de válvula fijo.
