The Model 660-B is a premium hatch designed with a round base and cover and is intended for use in applications where tight sealing is critical such as sour crude/gas or where strict environmental emissions standards are enforced. The Model 660-B is provided with a bleeder attachment, making it possible to relief tank pressure before opening the hatch. The bleeder prevents a spray from discharging when the hatch cover is raised.
