A-T Controls Series 90 Flanged Full Port Ball Valves

The A-T Controls Triac Series 90 is a flanged, full port ball valve available in sizes 1/2" to 12". The Series 90 has a split body design and investment castings. It uses a live-loaded packing system of Belleville washers, "V" ring packing, and patented pyramidal stem seal for superior leak protection.

This series has an ISO 5211 actuator mounting pad and is available in 316 stainless or carbon steel. Reinforced RTFE seats are standard, but other materials are available (Call Lesman for details). The 50/50 seat option can be used for high temperature and more difficult applications such as steam.

The Series 90 is easy to automate! See pneumatic and electric automated datasheets for pre-sized assemblies
