Another name for a _______-way valve is a multiple-position valve.

A four-way valve is indeed referred to as a multiple-position valve because it is designed to control the flow of fluid in multiple directions. This type of valve can direct flow from one input to multiple outputs or vice versa, which is essential in applications such as pneumatic or hydraulic systems where the manipulation of flow paths is required.

The term "multiple-position" highlights the ability of the valve to connect to different lines or chambers, allowing for complex routing of fluids. This versatility is particularly useful in systems where various operational states are needed, such as actuating cylinders in different directions (extension or retraction) or controlling multiple actuators from a single source.

In contrast, two-way, three-way, or five-way valves serve more limited functions specific to controlling fluid flow in one or two directions or managing specific configurations but do not encompass the broader capability inherent to a four-way valve.
