The A-T Controls Series 88 is a three-piece, full port ball valve. Available in 1/4" to 4" sizes in manual and automated configurations.
The Triac A-T Controls Series 88 is a three-piece, full port ball valve. These valves are investment casted and use a live-loaded packing system with Bellville washers, V-ring packing, and a patented, pyramidal stem seal for superior leak protection. The valve ends can be threaded, socket welded or butt welded.
This series comes in sizes 1/4" to 4" with a maximum pressure range of 1500 to 2000 PSI depending on the size of the valve. Standard seats for this product are reinforced TFE, but other materials are available. 50/50 seats can be used for higher temperatures and more difficult applications including steam.
The Series 88 is easy to automate! See specification datasheets for electric and pneumatic pre-sized assemblies.
