Oval manway A321
The A321 oval manway is a large structure designed to be built into the side wall of the tank. An external hinge allows the cover to be opened to the inside of the tank. A stainless steel butterfly handwheel makes it easier to smoothly tighten the cover and seal the entire assembly.
This model is made in AISI 304/304L stainless steel as standard, and in AISI 316L grade steel as an option. The wide range of elastomers used for gaskets allows the manway to be used in contact with a variety of fluids and liquids.
