installation and maintenance instructions for theclay & bailey mfg. co. thief hatches

operation of thief hatchClay & Bailey thief hatches are designed to provide trouble-free operation with a minimum of care and attention. The primary function is to prevent the loss of vapors in a closed storage system and provide pressure and vacuum relief.

installation of thief hatchThe Spring Loaded Thief Hatch can be installed on a matching API flange bolting circle of 16 bolt holes on a 10-3/8” circle for a nominal 8” opening. Place the base gasket on the bottom of the base and insert the 16 bolts from the bottom up by reaching inside through the opening in the deck and then attach each nut to the bolt from the outside. Tighten all nuts in a crosswise configuration making sure the hatch is fastened securely.

maintenance of gaskets and springsScheduled maintenance should be performed on a timely basis and more frequently in corrosive or dusty atmospheres. Normal maintenance requires the working gaskets and springs to be inspected and cleaned. Under normal operating conditions the pressure and vacuum gaskets and springs should be replaced once a year. The base gasket need only be replaced when a leak is noticed at the bolting area or if the hatch is removed.

general maintenanceTo ensure efficient operation of the thief hatch, the pressure and vacuum seats and gaskets should be wiped off carefully every time the hatch is opened. This prevents accumulation of residue that can deteriorate the performance of the valves.
