The Square Manhole Cover features a right-angled edge design, providing a larger opening area than a similarly sized circular one, facilitating personnel access and material loading/unloading. It is typically made of 304/316L stainless steel (hygienic grade) or carbon steel (industrial grade), and equipped with an FDA-grade sealing ring, making it suitable for industries such as food and pharmaceuticals. Its bolt-fastening or quick-opening structure offers unique advantages in space-constrained scenarios or situations requiring a large opening.

High Containment Powder Valve (also known as αβ valves) are used for the closed transfer of highly active and toxic powders to prevent material leakage and protect operators and the environment. They consist of an active valve and a passive valve, which must be connected to open. After separation, each valve seals independently, achieving an OEB level of 5 for sealing performance and an OEL of < 1 µg/m³. Made of 316L stainless steel and using FDA-grade seals, they are widely used in pharmaceutical and chemical industries for API feeding and IBC transfer processes requiring strict isolation.
