Oval manway A312
Oval manway A312 is a standard design for installation in the side wall of the tank. An external hinge allows the cover to be opened to the inside of the tank. A large plastic handwheel (standard) or optional M16 handwheel (INOX), make it easy to tighten the cover and seal the entire assembly.
This model is made of AISI 304/304L stainless steel as standard, and optional AISI 316L grade steel. A wide range of elastomers used in the production of gaskets, allows the manway to be used for a broad spectrum of working media (fluids, liquids).
