Gate valves are designed to provide a minimal flow restriction when fully open, making them ideal for applications where a straight-line flow of fluid is essential. The fundamental design consists of a valve body, a gate, and a handwheel or actuator that allows for manual or automated operation. The gate itself is usually flat or wedge-shaped, and its movement is vertical; when the valve is fully opened, the gate is lifted out of the flow path, allowing fluid to flow unrestricted.

The Fabricated Access Covers Trade Association (FACTA) provides its own specification which came into effect in 2013. It has a similar scope as the EN 124, focuses on wheel loadings and is based on the European standards for structural steelwork. The FACTA specification applies to solid top covers, recessed covers designed for structural or non-structural infill and surface drainage products.[30]

- Roadways and Highways Here, they manage runoff effectively, ensuring safe driving conditions by minimizing water accumulation.

- Roadways and Highways Heavy-duty metal covers are often installed on busy roads and highways where high traffic flow can exert significant pressure. Their ability to handle these loads while remaining intact is critical for maintaining roadway safety.

By increasing the convenience and security of bike parking, standing bike racks play a vital role in fostering a cycling culture within communities. When cyclists feel safe and have access to sufficient parking, they are more likely to choose biking as a daily mode of transportation. This shift can lead to a healthier lifestyle and a more connected community, where residents prioritize active transportation and the associated benefits.
