Bottom Discharge Assembly

Tank Flow

Discharge Faster, Clean in Place

The GQ80300 TankFlo bottom discharge assembly employs an armature to swing the foot valve’s inlet poppet clear of the flow path, promoting higher flow rates. Its downstream 3” butterfly valve pivots 135° so the assembly may be cleaned without removal from the tank. A 3“ BSP discharge spigot with tethered cap terminates the flow path.

The GQ80300 is made of 316 stainless steel with PTFE seals. An integral shear groove ensures the innermost valve remains attached to the tank and closed in the event of collision impact.
