Study Notes
Valve Symbols and Types
- Hand-operated gate valve: Symbol is a stylized "T" shape with two short lines. Description: A valve that's manually operated.
- Gate valve: Symbol is a stylized "X" shape. Description: A valve used to control the flow of fluids by opening and closing a gate.
- Closed gate valve: Symbol is a stylized "X" shape with a "black filled" portion on the "X". Description: A gate valve that is closed shut.
- Hand-operated globe valve: Symbol is a stylized "T" shape with a curved line at the bottom. Description: A valve that regulates flow in a pipeline.
- Globe valve: Symbol is a stylized "X" shape within a circle. Description: Manual manipulation for fluid control.
- Butterfly valve: Symbol is a stylized "S" shape. Description: A type of valve with a disc that rotates to open and close the valve.
- Control valve: Symbol is a stylized "X" shape with a curved line. Description: Controls flow in a pipeline.
- Back pressure regulator: Symbol is a stylized "triangle" shape with a curved line. Description: Helps to regulate the back pressure.
- Plug or cock valve: Symbol is a stylized "X" shape slightly rotated to horizontal. Description: A valve that uses a plug or round disc to control the flow of fluid.
- Check valve: Symbol is a stylized "Z" shape. Description: Only allows flow in one direction.
- Angle blowdown valve: Symbol is a stylized "X" shape with a diagonal line. Description: Used in systems where flow must change direction.
- Powered valve: Symbol is a stylized square with an "X" shape inside. Description: Valves that open and close automatically using a motor or another power source.
