What is the primary function of full-open valves on water supply pipes?

The primary function of full-open valves on water supply pipes is to allow for maximum flow. These valves are designed to fully open or close, enabling unrestricted passage of water when in the open position. This characteristic is essential in applications where the need for high flow rates is necessary, such as in certain plumbing systems, industrial processes, or when quickly draining a system.

Additionally, in situations where quick access to water supply is critical, full-open valves provide immediate access without the risk of partial flow restriction that can occur with partially opened valves. By ensuring maximum flow, these valves can effectively support the functional requirements of the system they are part of.

In contrast, other valve types may serve different functions such as regulating flow or preventing backflow, but a full-open valve specifically focuses on maximizing the flow capability within the piping system.
