255 Spring Loaded Thief Hatch
Features:
The 255 Spring loaded Thief Hatch is designed
to provide pressure and vacuum relief on liquid
storage tanks and reduce the vapor loss in a
closed storage system.
The 255 Thief Hatch prevents structural damage
to a tank due to excess pressure or vacuum.
The hatch opens to relieve excess pressure or
vacuum and reseats itself when pressure or
vacuum has dissipated.
