The Triac A-T Controls Series F90 flanged, full port ball valve has a split body design, available in stainless or carbon steel, in sizes 1/2" to 4". It is fire safe, API 607 4th edition certified, equipped with a live-loaded packing system, Bellville washers, "V"-ring packing, and a unique primary pyramidal stem seal that protects against stem leaks.
Reinforced TFE seats are standard, but various seat materials are available to choose from. The 50/50 seat option is available for services that call for higher temperatures and more difficult applications including steam. (Call Lesman for details).
The Series F90 is easy to automate! See pneumatic and electric automated datasheets for pre-sized assemblies.
