RIGHT SIDE UP THIEF HATCH
Right Side Up Thief Hatch
FAV Systems has engineered the Right Side Up Thief Hatch to eliminate problems associated with thief hatches in general. All other thief hatches incorporate a vacuum valve that is hanging in the thief hatch valve upside down. Being that the valve is upside down, all rust, debris, ice, water and any blow debris is sitting on the valve pallet, where if the valve opens, debris falls right in between the seat and the valve pallet causing continuous leaking. Once the valve opens, the chance of junk getting between the seat is very high and often happens.
