  • Replaceable Teflon Seals
  • Compact Design

The Betts 3” Top Unloading Valve is a hydraulically operated self-closing stop valve designed for installation on top of tanks which are top unloaded.  The compact design mounts to a standard 4” TTMA sump flange bolt pattern.  Valve is built with 316 stainless steel and uses Teflon and TEF-SIL encapsulated seals for compatibility with a wide range of products.

The 316 stainless conical stand-pipe adapter is mounted between the valve inlet flange and the sump flange and projects into the tank so that a stand-pipe can be welded in place.  The adapter is supplied ready to fit-up with a 2” pipe, but the conical design allows it to be cut back to fit larger pipe sizes as well.  Order adapter separately.
