Oval manway
A304 (305x430)
Oval manway A304
Oval manway A304 is a standard design for installation in the side wall of the tank. An internal hinge allows the cover to open to the center of the tank. A large plastic handwheel (standard) or optional M16 handwheel (INOX), makes it easy to efficiently press down the cover and tighten 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 variety of working environments (fluids, liquids).
The use of stainless steel oval manway A304
The main area of application is:
- food industry,
- beverage and alcohol production,
- chemical and biotechnology industries.
With good results, the manway can be used wherever the parameters of the materials used in its construction allow its application.
