Клапаны Swagelok^® с сильфонным уплотнением

Клапаны с сильфонным уплотнением ограничивают возможности протечек благодаря использованию схемы без набивки, и присутствию сварных уплотнений. Являются оптимальным выбором, когда отсутствие выбросов в атмосферу является критическим фактором с целью обеспечить безопасность операторов и надлежащее функционирование технологических процессов.
