Ball valves: These valves have a spherical closure unit that controls the flow of liquid or gas through a hollow, perforated sphere. 

Gate valves: Gate valves are designed to fully open or close the flow of fluid, using a gate or wedge as the closing element. 

Globe valves: These valves are used to regulate flow in a pipeline, with a globe-shaped body and a movable plug that seats against a conical seat to control flow. 

Check valves: Also known as non-return valves, these valves allow fluid to flow in only one direction, preventing backflow. 

Butterfly valves: These valves are used to control the flow of fluid and can be operated with a quarter-turn. They have a disc that is positioned in the center of the pipe for quick shut-off. 

Diaphragm valves: Diaphragm valves use a flexible rubber or plastic diaphragm to control the flow of fluid. 

Pressure relief valves: These valves are designed to automatically release pressure from a system if it exceeds a certain level, protecting equipment from damage. 

Safety valves: Safety valves are used to release excess pressure from a system to prevent catastrophic failure. has context menu
