A-T Controls Series D9 Direct Mount Flanged Full Port Ball Valves

The Triac A-T Controls Series D9 is a flanged, full port ball valve with a split body design and direct mount automation pad. The Series D9 valves use a live-loaded packing system with Belleville washers, "V" ring packing and patented, pyramidal stem seal for superior leak protection.

The D9 valves come in 316 stainless steel or WCB and are available in size 1/2 " to 6". Standard seats are reinforced RTFE, but other options are available (call Lesman for details). 50/50 seats can be used in high temperature and more difficult applications like steam.

The Series D9 is easy to automate! See pneumatic and electric automated datasheets for pre-sized assemblies.
