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.

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.
