Which feature does an angle valve have that creates a 90-degree angle between inlet and outlet connections?

• A. An additional inlet at the base of the valve.
• B. A built-in pressure gauge.
• C. A curved body path.
• D. An adjustable seat.

Answer: (A)

An angle valve creates a 90-degree turn through its port arrangement, specifically when there is an additional inlet at the base of the valve. This base inlet provides a perpendicular feed path, so flow entering from the base exits through the side outlet at a right angle. Other features don’t establish that directional change: a built-in pressure gauge is for monitoring pressure, a curved body path might bend flow but isn’t the defining port arrangement for the perpendicular turn, and an adjustable seat affects sealing, not the flow direction.
