GATE CONTROL VALVES

400H: Parallel Slide Valves (PARA-SURA)

Parallel slide has KOSO's own design/construction to realize very good and firm metal-to-metal touch sealing performance. Its execellent shut-off performance, brought about by the metal-to-metal sealing, makes it suitable to a variety of severe services, including emergency shut-off/opening at extremely low to high temperature.
