A three-way valve having two inlets and one outlet is classified as a:

• A. diverting valve
• B. two-position valve
• C. mixing valve
• D. pilot-operated valve

Answer: (C)

Port arrangement in a three-way valve determines whether flows are combined or diverted. With two inlet ports and one common outlet, the valve brings two separate streams together so they mix before leaving the valve, which is a mixing valve. If there were one inlet and two outlets, the function would be diverting, routing the same input to one of two outputs. The terms two-position and pilot-operated describe how the valve is actuated and how many positions it has, not the port configuration.
