An angle valve is essentially a globe valve within which the flow makes a 90-degree turn. It’s a linear motion valve designed primarily to stop, start and regulate pressure. They contain a disk capable of completely closing the flowpath or being totally removed from the flowpath altogether.
Angle valves are also designed with a stem that can move up or down to regulate the flow within the valve. They provide for a 90-degree change in flow direction, eliminating the use of extra fittings and elbows.
