The size of a gate valve is a critical factor, as it determines the volume of fluid that can pass through. A 150 mm gate valve, which is equivalent to 6 inches, is often used in larger industrial applications. This size strikes a balance between manageability and capacity, allowing for effective control of significant volumes of water, oil, and other fluids.
From a safety perspective, manhole covers must be secure and fit snugly within their frames to prevent accidental falls or injuries. The 750 x 600 mm size allows for a sufficient opening for workers yet minimizes the risk of unauthorized access or accidents, especially in busy urban areas where foot and vehicle traffic is high.
While recessed manhole covers offer a plethora of benefits, there are considerations that engineers and city planners must keep in mind. This includes ensuring proper installation to avoid structural issues or misalignment. Regulations may also dictate the specific requirements for manhole covers in certain areas, particularly in terms of load-bearing capacities and safety standards.
