| Gate Valve |
A valve with a flat gate that can be raised or lowered to control flow. |
Main water lines, steam systems |
Good for on/off control, minimal flow resistance |
Not suitable for throttling, slow operation |
| Globe Valve |
A valve that uses a globular body to control flow with a movable disk. |
Heating systems, regulating flow |
Good for throttling, reliable |
Higher pressure drop, can be more expensive |
| Ball Valve |
A valve with a spherical disc that controls flow. |
Water and gas supply lines |
Quick operation, durable |
Not ideal for flow control, limited throttling ability |
| Check Valve |
Allows flow in one direction and prevents backflow. |
Pumps, water irrigation systems |
Prevents backflow, simple design |
Can create resistance, may require maintenance |
| Relief Valve |
A safety valve that releases pressure to prevent system overload. |
Boiler systems, pressure vessels |
Increases safety, automatic operation |
Can be sensitive, may leak |
