What type of valve is required on a building supply to any structure?

A fullway valve is essential for a building supply to any structure as it allows for complete flow control and shutoff. This type of valve is designed to provide a straight-through path for the fluid, ensuring that there are minimal pressure drops and less turbulence when the valve is in the open position. This is particularly important in plumbing applications where maintaining adequate water flow is necessary for the proper functioning of fixtures and systems in the building.

In addition to flow efficiency, fullway valves are preferred because they typically offer more straightforward maintenance and ease of operation compared to other valve types. When immediate shutoff is required for repairs or emergencies, a fullway valve can quickly and effectively isolate the water supply.

Using a check valve is not appropriate in this context because its primary function is to prevent backflow in a system rather than control flow to a structure. Similarly, while ball valves are known for their reliability and ease of use, they do not specifically ensure the same level of complete control as a fullway valve in situations where total shutoff capability is critical. Globe valves, while capable of flow regulation, are not ideal for a main supply line due to their design, which can create pressure loss and inefficiencies.

Thus, the fullway valve is the most suitable
